The guys may resent Alice encroaching on their male-bonding time; now they have to class it up more than perhaps they want to (or so they think.)
One of the guys may have feelings for Alice but Cannot Spit It Out because they spend all their time rough housing. Alternatively, Alice has feelings for one of them but he sees her as one of his buddies, not as girlfriend material.
Alice accepts her male friends and their conversations at face value, fart jokes and all. She also doesn't "cling" to them. In turn, they don't resent her, even enjoying her company...and her advice on how to relate to women better if she has any.
Everyone knows where they stand with Alice relationship wise.
Played For Laughs: Alice becomes a "relationship advice" go-to, even though she just wants to watch football. Instead of the guys telling her to hold conversations until the commercial break, she ends up telling them that.
