earglesmackingjinglejiver
The sound you make when your brain is trying to cuss, but your mouth is trying to stay quiet, and it makes a loud, painful noise.
I tried to stay quiet during my mom's speech, but my earglesmackingjinglejiver ruined it completely.
During the church service, my earglesmackingjinglejiver was so loud, the pastor looked at me like I was crazy.
I let out an earglesmackingjinglejiver during my boss's presentation, and it made the whole office laugh.
