Every second word out of Ron’s mouth is a swear word and that’s a fact
I would also like to point out that Ron does “ a rude gesture with his hands” in several situations throughout the whole series
Now i can only assume that the rude gesture was a middle finger not a half-assed wave
So yeah ron has sailor’s mouth and i love it !!!
It was either the middle finger or the two fingered salute. For non-Brits, that’s this (as expertly demonstrated by Gary Barlow of Take That):
It’s a offensive hand gesture used almost exclusively in the UK. Legend has it that the gesture’s origins date back to the Battle of Agincourt.
