Spearmail 

sending an email to an unintended party; the result of which leads to a spear-like feeling to the gut for the sender, the receiver, and all the friends of both who see the email and wince in pain upon seeing such stupidity distributed.

Ed meant to send an email to Mike about the deal that Lea screwed him on, but sent a brutal Spearmail to Lea instead. When BMac saw the Spearmail he doubled over in pain and then busted a gut laughing.

Spermal Detonator 

A hilarious euphemism for any kind of nut shot imaginable...with a Star Wars twist!

I totally dropped a spermal detonator on my girl's tits and immediately went back to ruling at The Force Unleashed!

Venetian Spearman 

When you stand fully erect 15 feet from your bitch spread eagle and sprint full speed towards her hoping for full penetration.

I told that bitch to spread'em. The Venetian spearman is about to slay that puss.

Spearman sausage slapper 

The brand of hockey stick Mike Richards of the Philadelphia Flyers uses to play extra well in his games. Richards is the spearman and he uses his stick to slap the sausage (hockey puck).

Did you see that goal scored with the Spearman Sausage Slapper?

Steamrail 

The females's answer to the houdini:
In a steamy shower, the man holds onto the shower rail (or top of the glass panel depending on the shower) and bends forward. The woman wanks the man from behind.
The woman, unbeknownst to the man, then swaps places with a secondary man and slips out of the shower, under the cover of steam.
Man #2 proceeds to wank off man #1 and himself.
The woman then wipes away the steam from the glass (or pulls back the curtain) to reveal herself.

Man #2 then fucks man #1 in the ass, or if you will, "rails" him.

I had such a good birthday surprise last night, my girlfriend got me a "steamrail" from that top knot guy from the bar.
