Psycho Flex

Derived from the actions of the character Patrick Bateman from the film "American Psycho" ...

The act of flexing ones muscles and congratulating oneself in the mirror while having intense sexual intercourse. At some point during the flex off, the flexer must wink and point at himself in the mirror to acknowledge himself as being "Da MAN", even if his partner is not fully aware of the absolute awesomeness that has just rained down upon her.
If there is no mirror nearby, one may still perform the Psycho Flex, though the resulting ego boost may be greatly reduced.

The high from working out an drinking my whey protein had me Psycho Flexing all night with my lady. I think I pulled something.

Ukulele Flexer

A person (usually with a syndrome and no friends,) that thinks he/she is good at playing the ukulele, but actually sucks, and brings the uke to school and knows less than 10 chords, trying to show off.

River (to Josiah): Kyle is such a ukulele flexer.
Josiah: I know right. He sucks so bad.
Kyle Sweeny: Hey!
Josiah and River in unison: Shut up Kyle.

Flex

As far as urban slang, the definition is "to show off." Used by many rappers, most notable Ice Cube and the Geto Boys. Originated in the urban community, and has been used for quite some time.

"...no flexin', didn't even look in the nearest direction as I ran the intersection. (This is said because Ice is trying to get away from some people who tried to kill him the other day In the song, of course)" -Ice Cube, "It Was a Good Day"
