Top 5 Things That People Say Are Unhygenic (but I don't think actually are)

1. Not wiping your arse
2. Eating food when you've dropped it on the floor
3. Sex with animals
4. Picking your nose and then flicking your snot at other people
5. Paying for Unprotected Sex with 10,000 Venezuelan Prostitutes

Sticking yer finger up yer arse and then rubbing said finger across someone else's top lip,especially at parties where some poor sods crashed out pished and we've just shaved his eyebrows and cut his hair!

The five second rule applies here. Unless the food was wet, then it's only two seconds.

Back door, front door, back door.
