When a Euro or Russian pornstar sticks out her tongue to take the cum shot, and her tongue already has a thick white coating because she hasn't brushed her tongue from the last 300 cumshots.

Having a particularly dry mouth, especially whilst smoking. Also known as cotton mouth.
After I ripped that bong, I had a nasty case of Cum Tongue.
