But y tho 

But y tho is simple questioning something. It can also be the meme below, a variation of said meme, or a reference to the meme below. It's just a bastardization of "But why, though?"

John sees the above definition and is too dumb to figure it out himself that all he can say is "but y tho?"

A woman on whom backside attack is impossible due to bulkiness. The hindrance resulting is a case of too much cushin for the pushin. So named for inability of a tertiary alkyl halide to undergo the Sn2 reaction.

Guy: Oh man, Oprah is so fine. I'd doggie on that all day.
OtherGuy: Dude, you never could, she's a total t-butyl.

N. (mah-ree-uh boo-tear-sky-uh)

Russian figure skater (ice skater). Also known as "Masha". 1999 World Champion, two time Olympian, three time European Champion. Oldest Ladies' World and European Firgure Skating champion (ages 26-World Champ and 29-Euro Champ). Beat Michelle Kwan. Hottie! Looks like actress Eva Marie Saint (from back in the day).

I don't like Olympic-eligible figure skating now that Maria Butyrskaya doesn't skate anymore.

t-butyl 

A person, usually a woman, who avoids risque sexual activities, especially those involving a "backside" nature. The phrase derives from the tendency of functional groups attached to t-butyl to avoid participating in chemical reactions due to steric hindrance. Often affectionately abbreviated as t-but (pronounced t-buit).

Guy: Man that nun is hot!
Other Guy: Yea but I'm sure that she's a t-butyl!
