carrying out a series of small tasks while on the way out the door, delaying your departure. Fart arseing is often an infectious activity and can quickly spread across a group, severely undermining their ability to actually go anywhere.
Alex is really fart-arsing about now, that's going to make us so late...but actually while he's at it maybe I have time to redo my eyeliner.
