Shit test may not even be the right word, but i can't seem to think of a better one.

I like to consider myself an alpha in the making, ive been lifting for two years and am in excellent shape, but my social skills are lacking. On days when i'm feeling particularly beta i hide in a shroud of silence and revert back to learned behavior (Kino, eye contact, etc...)

But i digress.

In a few instances, but in one specific class i find that one individual tries to belittle and undermine me using his "smarts" in front of girls. I ignore it, but i don't particularly under stand it, i've never spoken to the kid and have made no acts of agression towards him...

My first instinct is to call him out on it, or try and intimidate him but i would imagine that would reflect poorly on me, if not get me in some sort of trouble (Read: Police State America).

What do?

Bonus Question: How do you reject a girl? On two instances ive been hit on by fat, ugly females, i sort of ignored it and hoped they "got the hint" (As a side note, it taught me a lot about what its like to be hit on as a female by beta males), my first instinct was to shoot them down by saying something along the line of "youre not my type", would that reflect poorly on me? How would one handle the situation?
