look up any word, like blumpkin:
to puke; throw up;

past tense: yes-yalled
"Oh man, he just yes-yalled all over the floor!"

Something rap should return to. Maybe it will, thanks to the Mos Defs, the Dels, and the Aesop Rocks out there.
We not ballin',
Or shot-callin',
We take it back to the days of yes-yallin'.
