haamushhnaagaa
The stupid noise you make when you forget someone's name and just yell it out like you're trying to impress them.
'Haamushhnaagaa!' *points at self* 'That was me trying to be cool.'
'Haamushhnaagaa!' *laughs* 'That was my brain doing a dance.'
'Haamushhnaagaa!' *waves* 'That was me, not my friend.'
