Rubbing the penis on the outside of the vagina or having sex with many women indiscriminately.

After oral sex, Mike pulled out his penis and began dickskimming.

"Hey Tom, heard you went dickskimming last night."

Covertly whipping out your junk and running the tip around the edge of a coworkers coffee mug ensuring their lips come into contact with your unit by proxy
