haamushhnaagaa
The sound you make when your brain short-circuits and you accidentally yell nonsense instead of saying someone's name.
'Haamushhnaagaa!' *facepalms* 'I meant Alex, not that stupid noise.'
'Haamushhnaagaa!' *laughs* 'That was not a name, that was my soul screaming.'
'Haamushhnaagaa!' *points at self* 'That was me, not my friend.'
