Random Tandem 

This is when two random things happen at the same time.

For example two complete strangers falling over in the same area at the same time. Or two people saying an unusual phrase at the same time like "I poke bagers with spoons" That is random tandem!

The Toronto Tandem Jump 

The Toronto tandem jump is a sexual act performed during a threesome that involves two males and one female. The smaller male of the two allows the larger male to penetrate his anus, and then proceed to lift him up and fuck him into the girl.

Dude last night I got the best of both worlds when we did the Toronto Tandem jump.

A penis and a vagina? You must have been lost in a carnal nirvana.

Ya and he made us both bleed.

The Tandem 

The act of simultaneously releasing the fecal matter from your anus and bustin' a nut (preferably on a girls face/chestal region). Is known to stimulate all portions of the genitalia and prostate at the same time, relaying the ultimate for of orgasm.

Warning: Evacuating your load at the exact moment the widest portion of dump passes through your rectum may result in a high enough pleasure to cause death.

Mikey tried to pull off The Tandem, but couldn't, due to the fact that he is a little sniveling girl who can't do anything right and will forever be known for his dinky dong, which is, by far, too small to, in fact, masturbate.
