hair wank - sneaking up on a grumpy old man with a bald head and snippin

sneaking up on a grumpy old man with a bald head and snipping off a piece of his hair and using it to jerk off while he’s too tired to notice.

I did hair wank on my grandpa and he just said 'I need a nap.'

I snuck into my uncle's room and did hair wank while he was snoring.

I did hair wank on my neighbor and he didn't even wake up.
