Boner-block 

When you try to jack off but you start to lose your boner because you can't think of anything or you lose your horniness.

John tried to jack off but he failed because he got boner-block.

Boner-block 

Boner-blocked
Original definition circa 1987
When a really hot chick is standing next to you in a year book picture and you want that hard-on captured for all eternity for her to always remember you by, and the person in front of you with a full head of hair blocks the massive erection, boner block.
Another derivation: Anytime you are posing for picture with a really hot chick, and the massive erection is obscured from the final photo, but there is at least two dirty grins on their faces

Billy: Gee I hope this massive erection I have right now makes the school yearbook, and this girl's douche bag boyfriend's see where her hands is.
Tom:Dude, how could anyone possible miss it?
Two months later.
Tom: Billy you totally gotboner-blocked, Lisa's big head of hair totally blocked the shot, but not everybody's grins.

Boner blockade 

The result of a disgusting act or acts of the opposite or same sex that is so apalling that a boner is lost. Often these vile acts crescendo into the blockade.

Thank god Kate wasn't smoking cigars and drinking hard whiskey. This would've left Jared with a boner blockade to contend with.
