a tail grab is when you grab the very end of your tails, a lot of people like to call it blunt so they aren't copying snowboarders. But in the one picture that guy is grabing in, he is grabbing toxic, and that is lame/stupid/not very cool looking! dont do them!
If we(skiers) are trying to copy snowboarders so badly, why then do we have two sticks under our feet when they only have one?
