A derogatory term for someone considered "socially inept" but still lovable. Someone who, although has a good heart and intentions, tends to fail immensely at every turn, and constantly put their foot in their mouth. An action performed by such a person can also be called a jeef.
"Man, you totally jeefed just now. I can't believe you called his mom a slut like that, Jeefy!"
It's a word that means jerk, fag, asshole, etc. It's also a good comeback for feejy.
