For example: SEXPLOSIONS!!!
Thus, why I am posting. I had just about the greatest and most fulfilling night of my life because my basic male desires were not only addressed, but simultaneously!
After a nice steak dinner, I went out to an action movie with a lady friend. It has been out for a little while now, so the theater was relatively empty. So with the stew brewing, we headed to the back row, and the little lady began to bob the knob. I sat there full and relaxed, young and hot blooded, taste of sirloin in my mouth, watching bombs detonating and loud explosions everywhere, adrenaline pumping from the action and our personal risky business. Explosions on screen while I was working on one of my own.
Hence, "sexplosion". Again, individually, totally awesome, but together, mind-blowing out-of-this-world awesome.
So, my humble recommendation to the reader is to try it out sometime: action movie + head = great time :)
