ICYDK: Crease is a slang word for funny (used in the UK)- full definition can be found here.
It’s incredible how (standard) censorship techniques – inserting bleeps over swearing and blurring obscene images – can be funny when mentioned techniques are applied to harmless dialogue & images – altering a scene to appear dirty & more fitting for a movie with an R-rating.
Daily Asgardian News (YouTube) uses the above techniques* for its Unnecessary Censorship series. The latest video (in the series) uses footage from Captain America: Civil War, it will make you crease throughout – watch below.
* – “Including a blur effect over the speaker’s lip movements to further sell a faux obscenity.” – comicbook.com
