I'm pretty sure it means lubing up with chip dip, eating half of a chip, and then putting the other part of the chip back into the container for some unsuspecting victim? And then you shake it all about, turn yourself around, and there you have it.
Really wish OP would explain what he means. Edit: Well, this is the second definition on urban dictionary...
do you genuinely think so? half these comments are variations of the same original comment. also, no, don't.
After reading that urban dictionary definition I'm gonna say know. But if you're going at it and can cum twice I think that's totally acceptable.
