Those words mean trouble – at least for one of the four women, who find themselves inside the Jersey Shore house after a night out at the clubs of Miami with Mike "The Situation" Sorrentino, Paul "DJ Pauly D" DelVecchio and Vinny Guadagnino.
In an exclusive clip from Thursday's episode, the guys invite two pairs of girls to their place and then devise a plan to ditch the one they're not interested in – the "hippopotamus" a.k.a. the "grenade."
While two girls wait in one part of the house, The Situation and Pauly D walk the other two past a sign that says, "In Miami nobody's ugly after 2 a.m.," and into another room, where they leave them to reconvene with Vinny.
"You two go in that room," The Situation suggests to his roommates, "and I will go in that room and I will extract the hot one. And leave the grenade to blow up in Ronnie's room by herself."
