When in the marines, you find a female creature (normally human) to have sex with. You bring them to a muddy space, dress both of you up in camo, but still exposing your genitals/or other fetishist need. Proceed to have sex in the mud.

Michael: Heh, that's why you're so muddy! You did a mucky camo din'cha.
