An abbreviation of both aggravating and aggressive. When someone or something gives you aggro, they're being a
pain or difficult. This can include being a precursor to violence.
Previously abbreviated to aggro, very
popular with the plebeians across Britain, but that was far too long for the commoners to say so it was abbreviated yet again to just three letters.
Nothing to do with
paintball.
"Dave's being a bit loud and obnoxious today"
"Yeah he's been giving me agg all day"
"I 'eard the
crew are lightin' up The
Queen Vic tonight"
"The agg has already started mate, Jimmy is getting shirty with
Bob before they've even walked in"
