Injeculated 

When you see something so incredibly cringe that your penis inverts and injects into your pelvis while while cumming. Basically a reverse ejaculation.

Bob: hey have you seen that Rebecca Black Friday song?

Jim: yeah man I injeculated the moment I saw it.

injaculate 

When a male reaches orgasm, and the ejaculate is forced to remain 'inside' or redirected into the bladder, either by clenching or physical manipulation through the taint. This can be physically harmful. First wirteen about approx. 7 years ago in the used to be cool till they sold at and went totally gay Vice Magazine.

I thought maybe if I didn't actually cum I could just go over and over again, so I tried that injaculate thing by pushing hard under my balls when I came. No cum, but it felt fucking weird. Like, taking a piss but with nothing coming out; just isn't right.

Injaculate 

When you go kaboom! And then you injaculate. You suck all the sexual juices back into your phallic member?

"Did you see Jenny injaculate?"
"Yep, she grabbed a fucking fly when she did it?"

Injeculate 

A perversion of ejaculate. It occurs when a guy reaches orgasm, discharges but is able to keep all of the semen inside of his urethra. Only a very few skilled men can do this.

Kashif got too excited on his flight and by accident released his load. Fortunately, he knew how to Injeculate so he was able to make it to the washroom without making a big mess.
