Happens after playing with yourself (aka whacking off) and not cleaning up properly with a tissue. After around 10 minutes your member becomes stuck to your underwear because of the excess semen excreted from your cock.
Dude, I had this awesome wank earlier, but 10 minutes later I had a willydribble, now i need lubricant to get my boxers off.
Reference to B-Ball, this refers to the leakage of semen postorgasm after one has pulled up their pants. It is characterized by an unpleasant, moist, sticky feeling in one's undergarments.
Fuck dude this sucks, I got double dribble all up in you know where.
Following an erection, sexual arousal may result in slight semen buildup in the penis. The soft dribbles occurs when the penis goes flaccid and this buildup of semen trickles out of the penis. This occassionally results in itching, tingling, and/or tickling sensation at the hole. A male may manually eject the semen by gripping the shaft and squeezing as he pushes along to expel the semen.
