look up any word, like rimming:
A scrotscratcher is one of those annoying cunts that without warning starts scratching their bollocks. Sudden and violent sractching is often a sign of std's such as herpes.

This will generally mean that the subject that is scratching his nuts will either be a dity stop out thats sleeps with any slag or his wife / girlfriend is the local bike.
Vicar, dont be such a dirty fucking whore shagging scrotscratcher.
