From your LINK Ultra Sonic 007 explaining what dirtboy called me.
Dipweed/dillweed. Literally, “dillweed” likens someone to pubic hair - “dill” being slang for “penis” (think dill pickle) and “weed” being slang for “hair.”
As in someone who doesn't notice taglines as she repeatedly asks who an FR poster supports.
You pick and choose from the definitions offered, I see.
Although I wouldn’t go for that one, I’d go for the first one: “Idiot; Bunghole; one lacking in intelligence or wit; inconsiderate”.
What can I say, it’s an urban dictionary.
