Pronounced "I'm Yuking." Means you are puking, vomiting, regurgitating, spewing, blowing chunks, tossing your cookies, tasting your dinner/lunch/breakfast for the second time(depending on the time of day), or projectile vomiting. To be shouted during the act. Derived from Ken and Ryu's infamous battle cry in Street Fighter when they throw the fireball.
