To let one go when suffering from serious windy-pops. A polite way of admitting your bodies emission, without using foul language.

It is not neccessary to wear a hat to be able to exclaim that you have dropped it.
Can also used by a third person as an accusative
"I must apologise to you all, I dropped my hat as the doors closed."

Or

"Did you drop your hat again?" said Roy
"No", said Dave, through the smoke rising from his smouldering trousers.

Get the Drop your hat mug.
Similar to "Boom head shot" this is yelled whenever one gets a head shot on another player.
Player 1 shoots Player 2 in the head, Player 1 then tells Player 2 "dropped your hat".
