You will often see this at highschool dances, night clubs, and Gay bars. The bumb and grind is basically a sexual tease if you see it up close or a far it looks like ur having sex with clothes on. In other words its a dance where two or more people dry hump eachother.
The bumb and grind is for people who can;t get any pussy at all
