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.

Someone who is as irritating as a weed growing in your dick would be. Especially within a short amount of time of being around that person. Usually someone that you know but is truly more accurate when used on a stranger that manages to accomplish said irritation.
