Texas Finger Trap

When two men are in the act of preforming a sixty-nine, a third party, wearing a ten gallon hat, begins to finger the two men's assholes.

Two penises approach each other. One circumcised and one not. The uncircumcised takes it for skin and rolls the foreskin over the other penis

when your doing double penetration with your friend and you pull your scooby doo out to finger the bitch, but when your fingering, your friend decides to jizz in the happy box with your finger stuck in the vag leaving you coconut juice all over your favorite finger

Two uncircumcised men glue their foreskins together, creating a liquid tight cock sleeve. Said sleeve will can be manned by either participant, or an enthusiastic volunteer. They then proceed to slide meat coozy back and forth at desired speed and vigor... simultaneous climax will assuredly follow. Once the shame sets in (as it always does in such circumstances), both men kill themselves or move back into their parents house.

Traditionally it is an ancient chinese finger toy. On the street it is used in reference to a girl that has been known to have sex with two men at the same time from both ends, hence resembling a chinese finger trap, complete with the pulling and pushing.

When you're fingering a girl, and she sneezes. This causes the tensing of the vagina muscles which can get your finger stuck up there! :D

Double teaming a dead body.
