arse-rider

An annoying prink who latches onto your exact walk speed and trajectory and then continues to follow you 'up your arse' all the journey. Can only be stopped with a sudden halt, which may result in a rear-ending, depending on how closely they are following you. Also applicable when driving.

E'yar mate this dickhead behind us is being a right arse-rider! He has followed us all the way home. I am about to slam on the brakes, hopefully he fucks off.
