look up any word, like donkey punch:
 
1.
A six or twelve pack of beer to bring to a party just in case they don't have enough alcohol, you know they will run out, or assume the only alcohol the host has left is Natty Ice.
Jason: Yo Ken, you think we should bring a safety pack to Chad's party tonight??

Ken: Um yea fo sho, the two Adam's are lushes and will be there early... they will obviously drink all the good stuff.

Jason: True story, safety pack on deck
