n., adj.: One who is made more uncomfortable in an already uncomfortable situation. Particularly in natural yet guilty-for-them social situations (most typically involving a situation with sex where they know what's up in their own right but can't let on, i.e. porn is put on in a social setting and they act like they're confused or offended).

She acted squermy when we discussed riding a train in front of her yuppie college friends but changed it up once they left.
They were really squermy as I schooled them on classic cartoon art porn in front of their revolutionary art peers. Fucking squerms posing. Learn your contemporary history instead of squirming around.
