(n.) Pr. (`twente` Fo'r-gE) The massive conglomerate of heterosexual boys forming a writhing pile on a couch. In this pile all members are furiously hugging and dry-humping the others. This outbust of erotic glee is the result of the climatic ending of an episode of Fox Media's television show 24 (mondays, 9-10pm) featuring Keifer Sutherland.
"After that awsome fucking episode of 24, Sean, Brian and Everett formed a Twenty-Fourgy on Nick's couch"
"After their Twenty-fourgy, Sean told everyone that they must never speak of it again"
