Weakness of both legs following sexual intercourse. Lack of leg power due to sex. Inability to jump after a good hump. Limp legs following strong dick.
Dude, what's wrong with you....you can't jump.... You've got kichi legs.

We had sex all night and now I can't even walk...I've got kichi legs.
I've got a big game tomorrow... I have to keep it in my pants or I'll get kichi legs.
