Cunts-On-A-String

Noun: Cunts-on-a-string: A long evenly spaced line of slow motorcyclists, bimbling along a winding road on the racing line at a fraction of the speed that would justify being on the racing line, completely oblivious to the presence of faster riders wishing to make progress. Cunts-on-a-string typically get very upset when faster riders overtake them and will often stop to remonstrate with them if the opportunity arises (for example, an impromptu stop made the the faster riders), but then think better of it.

The BMW cunts-on-a-string were most upset when Duncan overtook them on the inside of a bend
