Late arrival:
I'm not sure what your point is (only rational, consensus-voted pet peeves are allowed?), but okay: It's a glottal stop. For what it's worth, though, I think what we're talking about is at best a very soft glottal stop (i.e. "lay-uhn") rather than the glottal stop we all use (i.e. "layt'n"). Pretty nitpicky of me, but pet peeves are weird that way. Let me know if I should set up a poll, and I'll get on it.
Otherwise, what's with making this into a personal attack? I didn't say a thing about being vastly superior to anyone. On the other hand, your approach-- providing us all with a definition, calling me out on my pronunciation of words (I say mount'n, thanks), and beating this dead horse relentlessly-- is a little patronizing, don't you think?
Lord, dude. Go take a cold shower or something.
