When a girl is wearing large, men t-shirts that do not fit her, while going out in public or to a party.
Its Friday night and your at a party looking for that fine girl. Your friend comes up to you and points out the weird nasty girl. You ask who and he says the one (macked out).
We totally macked out that 'whatever', showing it taken over-the-top...like a kitchen loaded with top-of-the-line appliances, PLUS some other cool stuff.
When you've been wearing your mask for too many hours, and are sweaty, light headed, ready to risk fines or even COVID-19....well, ready to risk anything other that someone else's well being.
After being in meetings all day I am masked-out and just want to rip this off my face! I would rather stay socially distanced at home alone than have to wear this one more minute.
