While sitting in bed, one pull's their bed sheets up over their head to resemble a ghost, and masturbates underneath.

Can also be done with a flash light underneath the sheets to create the glowing ghost fap. The flash light illuminates the sheet creating a magnificent aural glow.
I scared the hell out of my mom last night, she walked in my room and thought she saw a ghost, turns out she only caught me mid ghost fap.

Get the Ghost Fap mug.
To fap in the midst of a discord/skype/etc. call without anyone knowing. Usually resulting in the person muting themselves if they are found out.
Bro, are you hearing this sound?? Ohh, George just muted himself.

Don't tell me he's ghost fapping again...

Get the Ghost Fapping mug.
When an event from your past haunts you while you're fapping.
Oh man, I can't stop thinking about her, she comes into my mind everytime I'm jerking off...she's like a fap ghost.
