He's emerged as one of the most popular Viners in the UK over the last year with a steady stream of public pranks, jokes, and stunts.
#SeeYaLater has become a meme on Vine, with hundreds of Viners balancing sunglasses on their heads to do their own Crascall impression.
He's even been the subject of fan art.
He's 32, from Dover, and since joining Vine in 2013 he's emerged as one of the country's leading social media stars.
He has more than 1 million combined followers across Facebook, Vine, Snapchat, Instagram, and YouTube, and could well become the UK's next breakout social media personality.
But Crascall himself is an unassuming character who works full-time in a bookmakers and has two children. He told BuzzFeed News:
I got into Vine because I was making videos on Snapchat and people kept telling me they wanted to see them saved and on other platforms. I then had a friend show me Vine and it started from there.
The "See Ya Later" character is one I love and it's great to see how popular it has become.
Crascall has done some sponsored Vines and told us he hopes to do more in future:
My main goal is to keep bringing out comedy content, which is my sole focus right now. I'm always looking to do new things and keep my following laughing. This year I will be looking at longer content as well as my Vine clips.
