look up anything, like your first name:
8. 'splainin' to do
A direct allusion to the 1950's American sitcom, I LOVE LUCY. In the show, the American protagonist (Lucille Ball) has a husband (Desi Arnaz) who is Cuban-born, and who occasionally makes some unintentionally humorous gaffes with English. One of these is his curious pronunciation of the word "explaining", which he always pronounces "'splainin'".
A frequent theme on the show was his discovering an entangled deception of his wife's, whereupon he'd intone sternly to her: "Lucy, I think you've got some 'splainin' to do."

Today people use the phrase both as a fond allusion to a cherished TV show, but as a way to imply that another person is at fault with something and needs to come clean.
Example 1. When the rock group successfully showed that their record company had not promoted their poorly-selling album sufficiently, the suits at the company had some serious 'spainin' to do.

Example 2. My Rolex, my computer and my car are all gone... and you've got a bad heroin problem? I'd say you have some 'splainin' to do!
9. explaining tool
commonly a baseball bat; possibly any club type item.
He's so stupid I had to use an explaining tool on him.
10. swoosh
When a middle eastern passes by and all of a sudden you smell this strong curry scent from behind them.

no racism meant, just explaining the word.
Dude 1:"Dude, I just smelt swoosh! from somewhere..."

Dude 2: "It was that indian girl's swoosh passing by, gave me a headache"

no racism meant, just explaining the word
11. mansplain
A word typically used to imply that the previous speaker is overly condescending and/or has a different way of explaining because he happens to be a man and the other party a woman. Usually, this is based in an over- or misinterpretation based on prejudice about the alleged mainsplainers intentions or on an inability to take constructive feedback. Sometimes it is used as an attempt to unfairly discredit the speaker or his arguments without having to provide counter-arguments. Typically, the mansplainer is simultaneously implied to be sexist or misogynistic.
Explainee: Women only earn 80 cents for every dollar a man makes. This is a grave injustice.

Explainer: That is a misleading statement. In fact, after correcting for factors like hours worked, experience, physical danger involved, etc., the differences is just a few percent.

Explainee (sarcastic): Thank you for mansplaining! I would never have thought of that with my tiny little brain!
12. Quelfing
When you touch your own "private parts" then without cleaning, explaining or warning, touch someone else, preferably on their face.

13. Kofiing
Kofiing is where a person will go to their boss explaining they have finished their work with the hopes of going home. Then said boss will pile on additional work. May also happen when asking your boss for clarification of a job or assignment.
"I just sent an email explaining I'd be done with the job by COB , so they kofiied me with another job assignment"

"I just went to say good bye but they are kofiing me with another job"
14. drunksplain
Drunksplain, -ing, -ed. The act of drunkenly explaining something. This commonly occurs when an individual, while holding an alcoholic beverage, attempts to expound upon his/her opinions/ideas/experiences. This person will usually lose track of his/her train of thought and will never reach the point originally intended.
Tim spent about two hours last night drunksplaining his views on the state of marijuana legalization in the U.S.

They're over there trying to drunksplain to the cops why they were driving in the wrong lane in the middle of traffic.
