I'd like to have a key binding for the "falling to death" scream, not just the default gesture

Taunt is fine, and I have it bound in quick access as it is one of the most important buttons, IMO, but often you need to express the opposite.
For example, you've been fragged centimeters from scoring, or see a guy running at you with both bfg
and quad, or express how much you are scared of that pro who is pwning you like a wet kitten... There are lots

Also, may it be possible to bind "meme-faces" so that your head is replaced with a camera-aligned rageface, or trollface, or whatever - just make the crosshair disappear while this is on, or make it have a noticeable cooldown so it doesn't get abused
