Slegging is the act of pulling the ends of your skinny jeans up to just below your knees to display your long and thick leg hair. The act of slegging generally involves a very special walk that can not be described by words in any way. Slegging was invented on some loser'S YouTube channel that generally hasn't taken the interest of any person.
Did you see that guy slegging?

Yeah I saw him, his legs were pretty hairy like a gorilla and I felt a huge attraction to them sexually as a result of seeing the hairs move them way they did when he professionally executed that walk I can't describe.

sleg. Something used by people who have no idea what to say to something someone said. Many find this usage confusing, but sleg can be used in any situation!
