Cum Run

The act of running to the bathroom after receiving a cum wad. Typically trying to make sure it doesn't drip to the floor or run down your legs.

The run from bedroom to toilet after sex, because you have just been ejaculated in.

"The Cum Run" is what you call it when you run across the hallway to the bathroom while covered in your own ejaculate. This would occur when you have forgotten to bring tissues to clean up after masturbating. (The running part is to prevent cum from dripping on the floor.)

when one is hanging out with a female friend (girlfriend, random chick, hooker ect.ect.) and engages in sexual activities. (blowjob/handjob)

Then after ejaculation occurs, the person leaves without paying, or returning that favor.

that moment when you have jizzed over your hands and haven't got any tissue so you have to leg it to the toilet to wash yourself. Mainly for guys.

To ejaculate during an "imtimate" IM conversation with a stranger and block them immediately afterwards.

to cum on a girls face after intercourse, and quickly grab your things, run out, and never return again.
