show boner 

A penis that has been deliberately coaxed to a state of partial erection so its owner will appear better endowed than if it were completely flaccid (yet not like some sort of pervert, as he would were it completely erect)

Nyquilla busted in on me dropping a deuce and saw my johnson before I even had time to work up a show boner.

Snowboner

When a snowboarder gets aroused from the epic weather and other snowboarding conditions. In addition, if a fellow boarder does a totally awesome 1080 rodeo flip, that could lead to a snowboner.

Bro: Dude, we got like 12 feet of snow last night. It's awesome bro. I'm going to triple backflip on my first run. You see all the snow on the mountains brah?

Brah: Bro, your story just gave me a snowboner.

Showbone

When a television show is so good it gives you an erection.

The season finale of Dexter gave me a raging showbone.

Snowboner

When a snowboarder is aroused from epic snowboarding conditions.

Bro: Brah, we got like 9 feet of snow last night. Today is super sunny and perfect. I'm going to shred the halfpipe while rocking my epic goggles. Epic conditions! Did you see all the snow on the mountains brah?

Brah: I just got a snowboner.
