When you don't want to tell someone who you had sex with the past night, sometimes out of embarrassment.
John: Hey, did you hook up with anyone last night?
Bill: Yeah, I did.
John: What did she look like?
Bill: None Of your Jizzness!
Bill: Yeah, I did.
John: What did she look like?
Bill: None Of your Jizzness!
