milky slap

When one slaps his ejaculated penis in another's face smearing cum everywhere.

Dude, I totally gave your sister a sloppy milky slap last night.

milky slap

The act of slapping one in the mouth with a penis after the mouth has been filled with ejaculate.

Randy's leg looks like somebody just gave it a milky slap.
