Twerk- Shaking your !%* in front of your webcam and uploading it to the internet while your parents think you are doing homework; even better if you are oldenough to not have to be overly concerned with your parents opinion anymore and therefore take it to a further extreme
But when I was in school, the boot skoot and buggie was big too
The Harlem Shake was a good one that fused some locking, popping, and house influenced moves into one flowing dance.
We have tried and true dances that have been kept alive because they look good and are fun to do (popping, locking, house, salsa, ballroom, break, etc...). Thenew dances that are coming out now have no flow, no style...Its just a bunch of jumping around (i.e. jerking). ugly.
