when a girl decides that she is not going to swallow when you pull out of her mouth to blow your load you shoot it up in mid air next to her face then while it is still airborne you in one motion slap the cum flying through the air and her face.
"dude... i totally airborne cum slapped your mom cause she wouldnt swallow my load. it was hard to do but i caught all my cum in mid air and slapped that bitch so hard across the face."
"but dude my mom swallows..."
"she didnt for me this time so i gave her an airborne cum slap"
