i hate seeing girls eat
like even on a date or somthing
wish they would just let me eat and get a drink or something 
Just say to them, "Its a waste for you to eat this as its just going to turn into turds anyways".
I say that one to Jezebelle all the time. Especially when we are down to the last serving or so and only one of us gets it.
Also, what particularly bothers you about them eating? Is it the pre-meal anticipation and the awkward waiting time, or is it the actual mastication?
