When water splashes back up and spritzes your a-hole after taking a dump in a public toilet.
"I had no other choice, so I had to take a number 2 in the mall bathroom. Unfortunately, I heard the familiar plop that could only be followed by a hobo's kiss. I now have some sort of ass disease, I'm sure of it."

Get the hobo's kiss mug.
Super intense kissing, like normal kissing, except dirtier (and sometimes bloody, that's just what happens when you don't have a dental plan)

(warning: hobo kisses can induce stabbing and robbing you of everything in your pockets)
Jeff: Sally is sure a good kisser
Steve: did she give you Hobo Kisses?
Jeff: HELLZ YEAH
