jacktation 

When a woman masturbates a man's penis with her breasts. (derived from the word "lactation," when a woman secretes milk from her breasts.)

Rick was tired of handjobs, so Barb got him off with jacktation instead.

JayStation 

A Canadian douchebag who creates clickbait "3 AM" videos for his twelvie audience and literally faked the death of his girlfriend for views. Also got in trouble with the law multiple times, dropped out of school while he was only in ninth grade, and claimed stolen valor. As of now, he has not created any new videos on his channel. Hopefully, that's the new status quo on YouTube.

Basically, a quintessential DoucheTuber.

Many other DoucheTubers have been inspired by JayStation's antics, such as N&A Productions and Stromedy.

Premature Send-jaculation

When you send an email before you're ready to send.

You might hit send accidentally or your cat walks on the keyboard and sends it for you or the next thing you know, the email has been sent even though you haven't even touched the keyboard.

The prematurely send-jaculated mail definitely isn't ready to be sent as it might be halfway written, have a lot of typos, or be too rant-y or stupid to be sent, hence causing embarrassment when the email reaches the recipient.

Co-worker to another: I just hit the wrong key and sent half an email to the boss that I shouldn't have!

Another: Premature send-jaculation is dangerous, hope you don't lose your job dude
