When straight dudes feel, by virtue of their strong heterosexual presence, that they will bring superior straight vibes to an otherwise perceived-to-be-gay place. Opposite of Gay Up the Place.
when describing a female, means one of two things:
1. she's fat: literally popping out of her clothes
2. she's popping out in all the right places (t + a)
"whoa--look at that one over there"
"day-um! that shit is poppin' out all over the place!"
