date hijacking 

When you're on a date with someone (this usually happens with a boy taking out a girl) and your date is snatched away by someone higher in the food chain.
Your date eventually returns to you hours later for the sole purpose of giving her or a him a ride home.

At prom, Mark got his date hijacked by Juan. She came back when it was time to go and Mark had to drop her off in Butt Fuck Egypt.

hijacking-off 

When your teledildonics network connection becomes compromised by an external third party (the telehijacker) and they gain control of your teledildo. Results in loss of control of a virtual masturbation session.

"Honey, you worked me so hard last night with the We-Vibe!"
"What are you talking about...? I didn't even have my phone on me last night..."
"Have you updated the security on your phone? Have we been hacked...? Was that a hijacking-off?!?!"

Thread Hijacking 

When a person starts a posting on a message board, or forum, or Facebook, that others are able to comment on, that original posting and the comments on it are called a thread. A thread hijacking occurs when one or more individuals commenting on the original posting, go off topic, creating a separate conversation. This is rude, and bad internet etiquette. If people want to discuss a different topic, they should start their own thread.

Below is a thread, consisting of an original posting and comments on that original posting. They illustrate a thread hijacking.

original posting: I'm so excited that my cat has learned to use the toilet with City Kitty! The training seemed like it took forever, but it's so worth it to not have to deal with a litter box any more! Has anyone else done this?

comment 1: Ugh! I just started training my cat, but he can't seem to move beyond the orange stage. How'd you get through that?

comment 2: I'm training my dog at PetCo classes. She's very smart. She learns the commands faster than the other dogs.

comment 3: I'm training my dog in PetCo classes too. They have great trainers. They're patient with the dogs and the people.

Comments 2 and 3 are off topic and are hijacking this thread. The person who made comment 2 should have started their own thread. The person who made comment 3 is guilty of continuing the hijacking.

Them: Sure!
