Boardslide
Boardslides are another fundamental trick. Like the 50-50, it is one of the first tricks learned. When boardslides are done, they leave marks on the underside of the board. Sometimes, people will intentionally rub their boards on hard surfaces to make marks so other skaters think they are not “posers”. So the motivation for this logo is to show that these marks are like badges of courage, and that the skater earned them and didn't fake it.
