occupation grunt
A low growl or snarl that comes from a man in a stall when he hears someone else walk in. It’s like the stall is a war zone and he’s the last man standing.
'You're not getting in here, I'm still peeing!' he growled.
'I'm not done yet, and I'm not letting you in!' he hissed.
'If you try to open that door, I swear I'll come out and beat you up.'
