underhanded comment 

A snide statement that is hidden behind what seems to be a polite one. It can be an inside joke, but can also have negative connotation.

Chris Brown: “I f--- with Frank Ocean! Reminds me of a young James Fauntleroy or Kevin Cossum”

Frank Ocean: “i f---s wit chris brown, reminds me of a young sisqo or ike turner.”
“i just dont like underhanded comments. thats all im saying.”

Underhanded Hitler 

Named for the motion as well as the signature Hitler mustache the motion creates, this euphemism involves an underhanded "zig heil" arm movement with an end result on your significant other having a Hitler 'stache.

Said to your friends at work in an extremely roundabout way:

"While we were experimenting with the glitter sack the previous day, I am currently trying to surprise her with an Underhanded Hitler."

Underhanded Bulgarian 

While sitting down, an individual reaches under their leg and masturbates.

I didn't have enough time to give myself the Stranger so I 'rassled up a quick Underhanded Bulgarian.

Underhanded Mustard Russian 

A crappy throw, toss, etc., where the person tossing the object misjudges the throw and completely misses the intended recipient, target, etc.

Lorenzo: "T-Bone, toss me a can of beer!"
T-Bone: "Here ya go!" (Throws beer 3 feet to the left of Lorenzo)
Lorenzo: "Dude, that was an Underhanded Mustard Russian if I've ever seen one!!!!! Now the beer is ruined!"

underhanded fastball 

Jerking off in a public restroom stall while doing a handstand. The ejaculation must take place in less than 15 seconds after the jerking commences, and to truly perform this dead the load must be caught in the mouth of the one jerking off.

Dude I passed this girl walking through the mall yesterday. I got so hard I had to go into sprint to the restroom and pull an underhanded fastball.
