Spontaneous Combust-a-nut 

When you see a girl so hot, that you cant control your man parts, and you jizz in your pants unexpectedly

That girl walked past me and as i watched her walk away it made me spontaneous combust-a-nut!

The Stripper was grinding on me and before i knew it, spontaneous combust-a-nut
