a gathering of males, typically straight, who gather and sleep in one place, usually due to excessive drinking during a "guys night", (variation on slumber party)
Man, we got wasted at Toby Kieth's I Love This Bar (and grill) and just had a lumber party at Dan's afterward since no one was in shape to drive.
Similar to an all-female "slumber party", a lumber party is an overnight between male friends.
Lumber refers to dicks. All male party=dicks. Therefore, lumber party.
Similar also to a "sausagefest", but a sleepover.
Tim: Dude did you go to Tom's sleepover last night?
George: Naw man, that was a total lumber party.
a homosexual sleepover

A lumber party is when you have 12 beautiful girls hide around the house you're staying at, and you "lumber" around and try to find them. Usually teams are broken up into single digits and then the person who finds the most women gets to sleep with each one.
