For everyone here who's not familiar with my Laughter Fed Vampires, I will elaborate:
Laughter-Fed Vampires (created by my lovely beloved) are vampires who feed primarily on laughter. They can survive for a long time without it, but it does affect them emotionally, mentally and physically (in that order). Any kind of laughter can work, but tickle laughter is more filling and 'tastes' better, especially with people they're close with, and especially when it's from tickling their 'victim's' worst or favorite spots. The happier the laughter, the sweeter it is! As a result, most LF!Vampires end up being major lers with their loved ones, especially if those loved ones are already okay with being tickled, at least by them
For example, if Reginald is an LF!Vampire, he'll mostly go after RHM, targeting his neck specifically (yes I have some very specific hcs, shut up/silly)
