A social booby trap, usually set on purpose by a host intent on making sure you're available for their
lame or otherwise undesirable event; most often set in
person, in the
flow of an otherwise harmless conversation. One should be on the lookout for this trap, and have a few handy excuses on hand to preempt or avoid making oneself unintentionally available. Trap is most effective on the honest, the sympathetic, and otherwise nice folks who can't just say "
F**K off!"
Host: "Hey, great t-shirt!"
Prey: "Thanks....I made it on Cafe Press."
Host: "
Cool. So are you in town this weekend?"
Prey: "Yeah, we
don't go away until next month."
Host: "GREAT! Then you can come to my SmurfExchange Party on Friday night!" **BLAM: Prey has just become a victim of invitational entrapment, and now must attend
lame event.
