Where a clump of poo gets stuck to your anal hair. You grab hold of said poo and pull it until it is removed. The poo takes with it a number of anal hairs during the removal which when placed in the palm of your hand looks like a spider. This is now a bum spider and can be used to chase your mates around and you will get similar reactions as if it was a normal spider.
Look at the size of this bum spider I just took out of my ass crack.

Where you pass another car and notice someone fit inside.
Once passed you move back into the same lane and casually allow your speed to reduce, enough for them to then overtake.
Once they complete the manoeuvre, you then retake said car. This is now a motorway dance and can continue to amuse both participants until you journeys diverge.
I saw a fittie driving on the motorway the other day and we did the motorway dance until the next services where u got their number.
