One-upmanship 

Is the art or practice of successively outdoing a competitor, rival or enemy/friend.

X: aww i like kati
y: ohhh yeaahh...you doo do yaa (he (y) doesn't like her but just wants to ruin the chances of them getting together, so behind (x's) back gets her (Kati) to go out with him, X is annoyed about them getting together but pretends its not bothering him, meanwhile X is using the same M.O 'method of operating' to get one back.

The one-upmanship escalates until either one stops, or they realise there both at it..(which would quite amsuing for them, or embarrasing.. depends how you take it ;)

One-Upmanship 

Expression to describe the dedication shown by someone who is amazingly sentimental with their passion to "one,-up" an opponent, who may or may not actually be concerned with the ability of the former.

"Yo, I tried to get a handful of them zoom-zooms, but several trust fund bitches were all about that one-upmanship, offering over cost for a bulk amount that should receive bulk rates.."

Faggot One-Upmanship 

When gay guys compete as to who can be the most gay.

After Biden went out of his way to appoint tropishly gay individuals to his administration, Trump praised Arnold Palmer's cock in front of a crowd and then lived with Elon Musk for four months in a the most embarrassing game of Faggot One-Upmanship ever played.

one upmanshit 

A phenomenon that occasionally occurs in social gatherings that devolve into a nostalgia-fest conversation about fecal incidents such as soiling underwear, quality bowel movement and/or alcohol fueled defecating incidents. Inevitably, the conversation becomes a string of awful fish-stories about large bowel movements and creative placement and/or uses of them. The conversation becomes more and more repugnant at a exponential pace. Ultimately, the least attractive person of the coversation wins with the most horrifically grotesque story about his or her colon meat.

"...Last week, at Joe's bachelor party, Eric told us this story about crapping his pants on the way home from work that week. For some reason, the stripper decided she should become part of the conversation and told a story about how she once deuced through her g-string thereby cutting the turd in two. Eric rebutted by regaling us with a tale of a boat trip where he made some starboard diarrhea or something like that. That touched off about an hour of one upmanshit where each had one less appetizing story after the next...."

Oneupmanship 

An obsession with the lives of others, combined with an extreme inferiority complex, resulting in a mental disorder that requires the sufferer (the Oneupman) to constantly feel the need to prove his or her self to anyone who will pay attention.

The boasts and claims of the Oneupman are actually a cry for help from an unconfident person who believes they are great simply for completing ordinary tasks faster than anyone else, possessing a higher number of certain items than anyone else, or for doing anything a higher number of times than anyone else. Sadly, the Oneupman is still stuck at the 'my dad is stronger than yours' stage of mental development.

The Oneupman never chooses a specialized activity to compete with, since they have very little special knowledge and simple 'accomplishments' appeal to them most, such as driving faster than you, eating more than you, and guessing how a movie ends before it ends. It should be noted that being the best is not the focus, the Oneupman is only interested in being better than YOU. They need others to compete with and prove themselves against, since they can't feel good unless someone feels bad.

Tellingly, the Oneupman will only compete with people they know, since competing with strangers whose skills they aren't familiar with may expose their weakness, which is the greatest fear of the Oneupman.

"Ok, in order to survive, we must both take one of these pills, and no more than one!"

"Oh yeah?? Well, I can take TWO, that's one more than you!"

"If you take two, you'll die, you idiot! This is not the time to practice Oneupmanship!"

"Oh, so you think I'm just average like you?? No way, I'm _______ (insert name here), I once _______ (insert exaggerated, unprovable claim here), I can handle two pills, ok?? Gimme those!!!"

Oneupman takes two pills and dies.

Oneupsmanship 

noun. The act or quality of being better, i.e. to "one-up" another. Someone with highly honed oneupsmanship is able to easily, elegantly and constantly one-up those around him or her. Frequently viewed with hostility and suspicion by those with poor onesupsmanship. Can lead to arrogance and condescension if overused.

Person A: I just bought a new car! It has a V8, it's so fast!
Person B (exhibiting fine oneupsmanship): I'm sorry, what were you saying? I was just polishing my Enzo Ferrari and I didn't hear you.

urban oneupmanship 

forwarding urban dictionary terms back and forth with a pal, each trying to outdo the other in sending the wittiest or raunchiest term.

I sent "girthquake" to Charlie but he sent back "butt weenie." I'm gonna send that pecker head "cum bread" and win this urban oneupmanship!
