The inadvertent, surreptitious, and often accidental placement of one's genitalia on another's person, usually the face or head.
"When you have a small dog that sometimes cuddles with you in bed, if you close your eyes for too long, you have to get used to the occasional dink across the forehead. You get used to such junk-slopping."

We all know what junk food is. And we know what happens to us when we make a steady diet of it. Junk sex is like junk food – not bad enough to avoid, but definitely not good enough to make a steady diet of. The effects of junk sex include outbreaks of unhealthy relationships and a malnourished emotional life, and self-destructive behavior like spending waaaay too much time at the gym. In addition to physical symptoms such as irritability, pain, and sexually-transmitted diseases. Junk sex, particularly media-induced junk sex, leads to a vicious cycle of empty sexual encounters and soul-sucking loneliness, and the obsessive preoccupation with our skin. No hard-and-fast definition (pardon the pun) can nail down the exact occurrence of junk sex, but it is very real and each person must define it for themselves.
