First step of three in beer pong leading to being "on fire"
After making one cup, a person may say I am pre-heating. If he makes their next shot, he will be "heating up." And if he make their next shot after that, he are "on fire"
Coined by the famous Marshall Finkelstein.
Marshall: Yo it's my first shot of the game and am already pre-heating.
Ian: Bro so am I!
Christian: Pre-heating muthafuckaaaaaaaaaaaa
