In the act of sexual intercourse, with one of the participants thrusting too hard He/She will let off an amazing amount of gas and in some cases following through (see drawing mud) this always results in the other members in the room trying to escape the stench and one member having no other option than to take a shower.

Debbie:- that was a Sexual Holocaust moment.
