The greatest thing known to man. A Supernova, also referred to as a "Rock Job", or, "Pop Rock Volcano", is the act in which a dame gives a bro a domer with Pop Rocks candy in her mouth. This is something that should be on anyone's bucket list.
How'd things go with Megan last weekend?

Oh, it was all right. We only held hands. What did you and Ellie do?

She gave me a Supernova... And when she was done, her breath smelled like watermelon.

When you're on the toilet and have to go number two, but you're horny and decide while your in there you'll multi-task, and well, out comes the johnson.
Now timing is everything with this, few have ever succeeded, many will try, but if you do it just right you can cum and drop a deuce at the same exact time; but, there must be simultaneous release, or your just a weird guy crapping and then jacking off.
That is a supernova.... good luck, and good for you.
