Go-go dancers are ladies usually 21 or older who are hired to dance on stages or speakers to hype up and entertain the crowd at clubs or raves.
Go-go's are often called strippers (which can be offensive to Go-go's) because they often wear bikini's and dance bra and underwear on stage. They are not strippers, they are dancers. Many people think Go-go dancing is easy, but it's like any other type of dance which requires skill and is much different than just partying with your girls on the dancefloor.
Go-go's often wear covers over their boots called fluffies and fishnet tights.
Girl (1): OMG that girl has some insanely fluffy boots!
Girl (2): Oh! The Go-go dancer? Yeah. I'd kill to party like her in those fluffies.
