Short for "Push Up"
When you are so diamond
cut and
ripped that you spend so long feeling the deep
burn that is a waste of energy to use both syllables in Push Up, as you have so many shups to do.
StupidPeanut: What your working on
today, big
man?
T-Dawg: Gonna be working the biceps with some shups.
50 shups.
Announcer: Who's gonna win this shup contest
