I've laughed to the point where I have had some serious breathing issues (my sister can get me laughing like crazy) it's especially embarrassing because instead of some deep, manly laugh I giggle uncontrollably.
It's a metaphor... of course nobody does it, but the symbology shows how funny you think it is...The Shadowlord said:This is an expression that bugs me. I always assume it's a massive exaggeration. I can't imagine anyone finding something so funny they literally lose control and throw themselves to the floor and start rolling around like they're on fire. But maybe that's just me, being the cynical pessimist that I am.
