Bubble swap

Normally delivered in the form of a question; a polite way of announcing the imminent release of digestive gases into a shared hot-tub, so as not to offend the ladies.
Sometimes becomes the OK for an impromptu group exchange of gases, to alleviate the silent discomfort built up by several members of the hot tub group.

Mixed group of people in a hot-tub:
Guy 1: "Bubble swap?"
Guys 2, 3, 4, 5: "Ahh, good on yer sport. 'Was holding that one in like a beer-chugg'n zeppelin."
<gaseous exchange>
Lady 1: Nice.
