A completely useless person that spouts constant bullshit

Male-directed insult. Also describes the tendency to rummage in your underwear massaging ones genitals as if looking for litter to pick up (hence womble )

The best insult known to man!

An idiot of the highest degree

(noun) A person, usually male, prone to making outrageously stupid statements and/or inappropriate behaviour while generally having a very high opinion of their own wisdom and importance.

synonyms: fuckwit, shit-for-brains

Male-directed insult: An unintelligent fucktard who has an opinion and a big mouth. Bullshit spout.

The literal meaning of cockwomble is someone who engages in cottaging or gay dogging type activities in public places. In general use, it seems to have lost this meaning and is typically just used as a general insult.

Wombles are fictional creatures from a 1970s British children's animation series. As the story goes, they live in a burrow under Wimbledon Common and get by collecting and recycling litter.

So if a womble is a critter that roams Wimbledon Common looking for litter, then a cockwomble is someone who roams Wimbledon Common (or other parks and public areas) looking for cock.
