It is when you are having sex and she rides you so good that when you pull out you nut powerful enough to paint the whole room and everything in it white.
Me: I was fucking this hoe raw last night and she was riding me like a Bugatti and I released the sonic blast and she was covered in my cum.
My friend: What?! I’m sorry dude. You need to find the right girl who could swallow it all.
Me: Don’t worry man I left that bitch on the front step for her dad to scoop her. Her dad will explain to her the importance of swallowing it all.
