A British slang term for the phrase 'Laughing' usually written with more than one g, used primarily among the lower class, who can't speak. Nobody really knows how this phrase originated, but here is my theory.

One day, a youth in a hoodie was sitting at the back of the bus with his hat backwards (we'll call him Stev). His friend was scrolling through his phone, when he noticed a funny video, it made him laugh so much that he folded in half and fell onto the floor. This reminded Stev of a paper plane he made earlier that day, he remembered how the paper folded in half and how he was creasing it to make it fly better. Stev, comparing the folding of paper to the folding of his friend, and with the word crease in his head, suddenly cried. "Yo, how funny was that vid mate? You're like, creasing" His friend thought that the phrase 'creasing' was pretty good, so told his friends about it, who told their friends and their friends, until the word was so popular, chavs used it on a daily basis. This is how creasing became the word we know of today.
Chav 1: "Mate that was so funny! I'm creasing."

Chav 2: I know right mate!
