A game in which two extremely bored people toss a hat on to each others heads. One person sits on a lofted bed while the other sits in a chair or on a coffee table. Lump is achieved after one person manages to toss the hat onto the head of the other person. Origins go back to 2004 A.D. after Cool Kyle gave a lame definition of the word lump as a smell of two people in the process of making out.
Zach and Randy played lump after Cool Kyle gave a dumb example of the word.
