passive aggressive lol

The act of using typing an angry(ish) message to someone but adding 'lol' to the end in order not to come off as angry/ irritated despite actually being angry/ irritated.

Emma: hey bbe, did u wash the dishes?? E xx

Dave: sry, been watching football. Will do l8r. D xx

Emma: u had better or I swear I will be pissed lol. E xx

A fine example of the passive aggressive lol.
