The grand slammer

The grand slammer is when you do a line of coke off a girls belly, kiss the girl, take a bong rip, take two syringes full of tequila then make out with a second girl and she slips a ecstasy pill from her mouth to yours. Then you die.

Yo man! Nick just did the grand slammer, his buddies had to take him to the hospital.
