Monster trying to get its teeth into you? Here's an unusual solution; force the creature's jaws apart until they break.
Oddly, this is almost always portrayed as causing instantaneous death (in which case it's usually taken to be a "cooler" version of a Neck Snap), when it should leave them alive but in crotch-stompingly horrible pain.
For some reason, reptilian monsters are especially prone to this.
A nastier variant is to simply tear the jaw off altogether.
For a less-brutal way of stopping a creature from biting chunks out of you, see Palate Propping.

- In an in-continuity special for The Bridge taking place back on Terra in the 1990s, "Godzilla Meets King Kong!", and we see King Kong use this. A growing Godzilla Junior, who'd been following and learning from Kong, uses it to finish off Gaw. The 'instant death' part is justified, as both of them finish the job by pushing the now broken jaw down and crushing the skull. Junior later uses it in the story proper on Grand King Ghidorah. While it doesn't kill him and he regenerates, it definitely hurts.
