...what the hell are they?

What made them so unacceptable?

When they were invented, did someone say 'ah, 'tw*t' sounds a little harsh, lets make it socially unacceptable for fun, then we'll call it our mums and laugh at her naiveity'

And who ranked them!?

Why are some more socially accpetable than others...

'Oh c*nt, that sounds a bit disgusting, lets rank that number one, champion of the swearwords. Pr*ck just got relegated to division one, and tw*t is on it's way'
