Fish eye
The act in which the fellow, performing intercourse with his gal doggy-style, pulls out right before orgasm, spits on her back or neck to trick her into thinking he ejaculated on her, then shoots his load into her eye when she turns her head.
"I had to wash my eye out," Mabel said, "after Ned hit me with the old fish eye trick. It's a good thing our supervisor didn't catch us."
