A genre of music, usually 70-90 BPM liked by teenagers with no taste in music. This music is played at sweet 16's where all the little kiddies form a circle in the middle of the dancefloor and grind on eachother at 70 BPM. ie. Lil Wayne or Mims
That new Crib Hop song is so hot I fingered Jessica at her Sweet 16 while her mother was eating dessert.
