Used to describe a scene of banter that is so fucking hilarious that you acquire crease marks on your belly from laughing so hard. Often, recipients of a creaser will be left crying and/or on the floor. It can also be used when a very dead joke is made, and someone could sarcastically exclaim that it was a “creaser”.
