Verb; To push a person, generally an ugly old woman, crone, hag, witch, etc., into something
hot, such as a
fire, hot coals, or an oven. This phrase is an homage to Grettle the Great, who defeated the infamous witch of the
candy cottage by heroically pushing her into a hot oven.
Dude, I totally grettled that bitch!
She pulled a grettle when she saved her
brother by pushing the
witch into the oven.
That
insult wasn't a burn, it was an all out grettle.
