What is kissing corns and if so how do you remove them?

A corn . Is a buildup of dead skin. Kissing corns are when you have this on adjacent toes so a corn on one toe matches up with acorn on the opposing digit. The corns can be trimmed or pared away but will likely grow back once the person puts their shoes back on. Shaving down the underlying bony prominence is how to get rid of this. This is not done by you, rather by a foot doctor.
