When you don't fully finish taking a pee, and you walk of and around 5 seconds later your penis drips warm pee into your underwear. Dick Drip can also be used as an amazing insult.
"Gotta get to work, need to finish peeing quickly. Done! Oh damn, I've got dick drip!"
A moisture and 'staining' problem associated with overly sexed men most typically homosexuals who want to 'pass for straight' but who wear extremely silky underpants to maintain a constant arousal state that results in 'pre ejaculate' more or less constantly leaking through the non absorbent slippery textured briefs...boxers...or 'man panties'...and causing obvious and humiliating stains on the front of the pants you're wearing........most men who suffer from this condition do not considered it a 'unpleasant condition'....although their presence out in public tends to turn heads and garner rude stares from other men who recognize this 'perverted behavior.'
Look at that buff bro! Can you BELIEVE he'd go out in public with such extreme 'dick drip'!!??
