A nick-name for one whose attributes are all of the above.
Tom: That guy is SO gormless, he really doesn't have a clue! It's actually hilarious to watch... from a distance.
Dick: Yeah, I really cant stand that guy! I'd NEVER invite him to a party.
Harry: Guys, chill, it can't be easy to wake up every morning and have to face not only the world but also yourself. Have some compassion for the dude; he's clearly got problems.
Brian: Sometimes I just feel so, so, SO gormless! Briana: Hmm, 'gormless', rhymes with formless, chormless, hormless...
Brian: That's not helpful.
Briana: Perhaps if you thought about your words before you spoke them... hmm? After all, the definition of a gentleman IS 'one who says what they mean and means what they say'!
"The man gormlessly(<-adverb) spent his life with his proverbial foot in his mouth; always the moment killer, cringe worthy comment maker, lie starter and shit stirrer. He had made many enemies out of friends and had a lot to atone for."
