Quit trying dodging the fact that you're probably 12 years old and have no idea what you're talking about. Maybe I wouldn't point out your grammatical errors if you bothered paying attention when you were in 1st grade and weren't such an idiot. And no, pathetic does not mean pointing out grammar flaws, pathetic means starting an argument then quitting because you know you'll fail.

Aww, is someone butthurt?

Well if you wanna get TECHNICAL:
adjective: pathetic

1.
arousing pity, esp. through vulnerability or sadness.
"she looked so pathetic that I bent down to comfort her"

That's not pathetic then, what he's doing is:
verb: retreat

1.
(of an army) withdraw from enemy forces as a result of their superior power or after a defeat.

I mean Hell, if we wanna split hairs, I'm built for that.
