Or the super ability to regurgitate your own words. The angrier you are, the larger they get. You in theory could use these solid letters to throw or hit people with- but your power is your very own weakness. If someone pisses you off too much or you stub your toe and go to scream "FUCK", asphyxiation will occur.
Or alternately the super ability to talk shit to people and launch fecal matter from your mouth. Once you run low on power, diarrhea just kind of dribbles out...
