Don't worry about it. Guys constantly shit test as well, to establish their dominance within the group.
If you've known them a long time, they'll probably see the old you as having less value than you currently do. All they're doing is trying to establish where to draw the new line's. How far you'll let them push, and how well you stand up for your values and idea's.
It's pretty much all just the bare bones of PUA. Not surprising since it's based on human behaviour.
In fact this literally happened to me earlier. Morning after a party, not slept. Another alpha of the group's in the kitchen.
Me: Who want's a cuppa?
Alpha: Sure. Tax not making it. (SHIT TEST)
Another guy: Tax not making it
Me: I'm clearly already making it. (Qualify myself - failure)
Alpha: That was the joke

(Neg)
Luckily i'm not that much of a AFC when i'm fully rested. But really, don't worry about it. Just as girls periodically shit test for congruence, guys do too.
