Cumthought 

That final piece of mental imagery which pushes one over the threshold towards a sexual climax... pertaining to the idea of ejaculation, the cumthought is that which produces, and precedes, the cumshot.

"Yeah man, I can always rely on imagining railing my girlfriend for my cumthought. Gets me every time."
