The Noodle Incident Meme
Technically it's not really for Noodle Incidents so much as Off-Screen Moments of Awesome but let's not split hairs. Noodle Incident sounds cooler.
Here's what you do:
1. Post with your character(s)!
2. Proceed to romp around other comments, inventing shenanigans, antics, misunderstandings and general faffery that your characters have been involved in.
3. In-game or in canon, doesn't matter as long as it's something that can be brought up in tones of nostalgia, horror or smug self-satisfaction later.
