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.
