The weed that a male keeps separated from the rest of his stash with the hope that sharing it with a female will help his penis find happiness and purpose.
John spent his entire bag of dickweed on some skinny blonde girl, and then disappeared - he's probably plowing her right now.

A weed that grows when the wind blows. Usually grown in the southern states, it has been known to grow well north of New Jersey. Dick weed spreads very easily from area to area, and can grow to huge sizes. It is best not to plant Dick Weed to close to Pussy Willows, otherwise you may get a crop of cumquats.
Did you see the size of that Dick Weed? Man is this place full of Dick Weed's.
