Brazillian Dancing

[karlhein]

I've seen recently on the 2nd channel of FB, videos of a guy singer, with a girl up on stage, she essentially dry humping his leg as they "dance", and with them making out pretty heavily between his singing.
I've been with enough ladies that could essentially get off dry humping and I've seen enough girls show their tits to the band, or come back stage after the show for some sucking/fucking, that I'm wondering if this is girls having orgasms in public.
Does it have a particular name? From the text comments, I think that it's in Brazil, but it's certainly South American. Anyone have any comments or stories?
