BUR #49508 has been rejected.

create alias footprint_on_body -> footprints
create alias footprint_on_face -> footprints

Similar to slap mark and slap mark on face.

BUR #49509 has been rejected.

create alias footprint_on_face -> footprint_on_body

This one depends on whether we find it more similar to facial -> cum on body, or to food on face which is different from food on body, with the latter applying to other parts of the body than face.

Footprints on body need to be separately searchable from footprints, it's something completely different, one implying abuse or degradation of some sort, the other can mean a lot of things in a scenery post, but not that.
