3. A feeling of ecstasy so great that ones molecular structure is shredded, in a flashy boom of fleshfetti.

1.
A combination of the words "explosion" and "orgasm".

To experience a very good, very fast orgasm, especially happens after you orgasm after being deprived from sex/masturbation for over a week.
My Wife's parents spent the week at our house and I had the worse case of blue balls ever, but the explogasm she gave me when they left was well worth it.
