Abbreviated "the flubs", Double Flubble refers to a specific sex act between two men and one woman. The two men stand with their backs to each other, while the woman kneels between them and reaches through their respective legs, simultaneously giving each of them a handjob. (Kind of like a backwards Eiffel Tower)
Pro's: the guys don't have to face each other, and technically it is a threesome
Con's: makes for awkward conversation while it is taking place, and most women find it degrading
Last night, Jane got really drunk and performed a double flubble on myself and another male. I have no regrets.
1. The act when a male is intoxicated and has sexual intercourse with somebody, and half-way through, he sobers up, realising his partner's physical features represent a decomposing trout inside a balanese prostitute, and as a result the male's penis then becomes flacid.
2. Noun. A word to describe someone who is likely to cause flibblegicking.
1. "Man, after the pub I went to this chick's house, but then I totally sobered up and flibblegicked!"
2. "Dude, Sarah is a grade-A flibblegicker..."
