Man, there's several phrases I've grown to hate hearing:
When belaying from below - "watch yourself, man, I think I might shit myself here" followed shortly after by a warning of "SHIIIIT!"
When on the crux of an 11b, fifteen feet above my last piece and twenty-seven feet above a protruding ledge, my belayer says, "hey dude, can you like stay put for a minute, I don't think I'm usin' this GriGri right..."
or, somebody I hooked-up with to do a climb after she tells of the .10's she's led, then, makes extravagant excuses involving her boobs constantly wanting to fall out of her top to explain why she can't follow on a .7
I hate hearing all of those bits.
