It is when the man ejaculates in the mouth of a femal or male so much that she or he is forced to swallow part of the cum shot and chokes a little on the rest of the hot load.
I surprised my girlfriend by not telling her when I was going to ejaculate in her mouth and she ended up swallowing and then gagging on the rest hence the term semen gargle
