The Gremlin Grunt

When you fuck someone so hard that they start grunting in an extremely deep voice, often sounding like a shitty Golem from Lord of The Rings. This low grunting will continue until your partner lets out a massive screech. Signifying their change into the Gremlin King/Queen, they are now the ruler of all Gremlins, truly a noble honor.

Yesterday Elizabeth transformed into The Gremlin Queen after she pulled off The Gremlin Grunt.
