A dance where the woman dancer runs or bumps her butt against the guy's penis. The objective is to get the guy to get turned on. Many guys who have no grinding experience worry about if they get a boner up the girl's butt, but it is in fact normal and quite expected. Most girls will love the feeling.

It is a very popular dance amongst teenagers and adults in their 20s, becoming commonplace at school dances and prom.
Lydia walked up to Runer at the school dance and asked if he would like to grind with her. He said yes, and they grinded together all night long. Lydia laughed as Runer got a boner as her big, round butt rubbed all over his penis. After grinding on him at the dance, Lydia took Runer to her house where she sat on his face.

The act of dirty dancing at a fast paced song with the opposite gender, sometimes with the same sex.

Two ways:
1) A guy takes a girl by the hips, moves side to side (hips) and she rubs her booty, while doing this, on his crotch until he gets hard. Guy has control over the girl at all times.

2) Another way to grind is to take a girl from the front and rub both of your crotches together. Same way as #1 but affects girl and guy instead of just the guy. This way is more sexual.
Megan: I grinded with Nick all night!
Cady: Really?!? Was grinding him good or did he get a woody?
Megan: He got one, but I liked it!
