A friend of mine seems to have a differing online persona/alter ego.......where he takes himself uber seriously & all his eggs are double yokers! The slightest whiff of mockery or pisstaking & he throws a hissy fit!
I remember thinking "I want to punch fcuk out of you" at one point but then remembered he's actually alright in real life so just blocked him instead!
Most of our mutual friends think & have done this too!
