Similar to a heart attack but the victim suffers numbness of the legs and a slowed heart rate and the craving for anything crunchy.

slackfish

what everyone wishes they could be but can't because the three 'slacks' Staycee Jessica and Cassandra are the only slackfishes in the world and word can be used only to describe those 3

Cassandra: "Slackfish I'm thirsty."

Staycee: "You're always thirsty slack!"

Jessica: "Do any of you slacks have any food?"

olympic slacker

An individual who, whether he or she knows it or not, displays great achievements in the slacker lifestyle. Extreme laziness, mild obesity, hygiene challenged, or combinations of all three are likely signs. Drugs and other special substances may or may not be related to the cause. It is more than likely that there not.

Man, I am such an olympic slacker. Its like what, five in the afternoon, I haven’t bathed, brushed my teeth, and I'm still walking around in my now smelly sleepwear from last night.
