The comparative term to the male "cock block." It means to effectively stop a female companion from getting laid.

I was gonna bring this hot guy back to my apartment, but my bitch roommate decided to pull a clam jack.

Slack-Jack 

A complete and utterly terrible handjob. One that is simply not worth the time and honestly makes one wonder what the fuck is wrong with with the human being who's head is in your lap.

Brady came back Jones' house and told everyone that Liz gave him the Slack-Jack of the century and he'd rather stick his dick in a pinecone than experience that again.

Blumpkin Jack 

The act of a crazy buff guy sitting on a toilet in the house of a dirty mexican while receiving a blumpkin by a Wizard of Oz character (preferably the lion or a munchkin).

Bryan: Whoa! You look you happy

Jake: I just got the best Blumpkin Jack from LVG!

Samurai Jack 

An awesome show originally released by Cartoon Network, but later released by the CN late night channel Adult Swim, it is about the young samurai, Jack and his quest of defeating the Evil Aku (the main antagonist) , (Spoilers!!) in the first episode he comes close to defeating Aku, but before he could he make the final blow Aku sent him into the future, where he terrorized the world and built robot armies to carry out his will. unlike most show the main bad guy does not have a one sided personality of straight up evil, as Aku is humorous as well. Samurai jack has been around since 2001, but just had it series finale this year (2017) because from 2005 to 2016 it was canceled by Cartoon Network and was finally picked up by adult swim somewhere between 2014 and 2017 where they made the show more for the adult age group. If you haven't seen Samurai Jack yet, I suggest you do

Long ago in a distant land, I, Aku, the shape shifting master of darkness, unleashed an unspeakable evil.
But a foolish samurai warrior wielding a magic sword stepped forth to oppose me.
Before the final blow was struck, I tore open a portal in time, and flung him into the future where my evil is law.
Now the fool seeks to return to the past and undo the future that is Aku.
Guy 1- Ever heard of Samurai Jack?
Guy 2- Yeah I heard of it but never watched it
Guy 1- Well you should its awesome
