The worst insult to a male, basically callin him a bitch or pussyboy but not in those words. You should be ready to fight after being insulted like that. It originated in the south. (also see fucknigga)
A person who is constantly making people's lives worse. There are many ways in which one can do this. That person is usually very annoying, a pussy when it comes to doing anything moderately badass, always exaggerates whatever effects mind altering substances have, will take things from you saying they will pay you back but never will, always bum other peoples things (food, gas, weed, alcohol), only wants to be your friend because of things you have that the person wants, etc. This term also goes hand in hand with hotboys, because most fuckboys are hotboys as well. (see hotboy)
friend: Yo dude sidon asked me to match him on this blunt
you: Cool how was it?
friend: When I got there, he said he smoked his weed and asked if I would throw down this time.
"Hey man, I just got fired from my job, my car got repossed, my wife is serving me with divorce papers, and my dog died...don't tell me to chill out; I got fuckbombed today!"
They are soulless little shits who can't get their lives together and feel that they need to take the happiness out of girls and ruin their self confidence just so they can be the "real deal"
