Now I'm not a vore fetishist, BUT my fetish unfortunately tends to overlap with it so I do see a lot of vore shit. So I can safely say that no, Santa is not a huge icon in the vore community.

Unless they're counting Santa outfits.

Capable of being anywhere in an instant, jiggles like a bowl full of jelly, traditionally placated with high calorie snacks, Orwellian overseer and passer of judgements, carries around a sack of theoretically limitless capacity, frequently blushing, 'bear' body type complete with big-ass leather boots, nobody's ever seen him (and lived???), carries around large quantities of flammable material for use on punishment worthy children, and Krampus has been mysteriously phased out in recent years.

God help me I can kinda see it.
