Thought Boner 

A thought so goode, so magnificent, that if you follow the thought one can see it ending in some euphoric state.
A thought, often times elegantly simple, that causes one to get excited. The thought boner is often detected by others when the thinker pauses mid-sentence and smirks.

A cross between a brain boner and thought bubble.

AM: "Hey did you get that work done?"

AM:......
AM: "thought boner about button...doing it right.."

Boner Thought

A thought that seems genius while you are erect, but becomes horrible after climax.

Guy 1: I thought about Skyping my ex and asking to see her butthole again.

Guy 2: Oh my God. Did you?

Guy 1: Nah. It was just a boner thought.
