I think it's really annoying when a woman screams out loud whilst she's being shagged. Take last night, she screams out. "Oh my God! oh my God! he's at the window again Jim!"
For fucks sake, it's hard enough as it is, clinging to a drain pipe with one hand whilst trying to have a wank with the other, without being put off by the silly cow screaming."

Downright fucking rude I call it.

PS.
I also think it's rude for deaf people to talk with food in their hands.
