Jack

An over the top kind of guy. Always is screaming at everything, and is always hyper. Making this... THING the most weirdest, but dumbest person alive.

Why are you so hyper? Your acting like Jack...

Stealth Jack

The use of the word is done so in which to trick someone during the game of Bullshit / Cheat / I Doubt It, not just restricted to jacks but to your personal favourite card. This is used to make someone think you are bullshitting, or to people that know you more well, make them think you are in fact not bullshitting.

You: Yeah I place down a stealth jack...I mean a 7
Silly Billy: Oh mate that defo bullshit you so put down a jack
You: nah m9 #dealwithit

or

You: Stealth jac...I mean a 6
People: You do that all the time now we know it is a 6
You: *gets a free pass for lying*

jack-in-the-bed

When your man TRIES to discretely jack-off next to you in bed, thinking you're fast asleep, when in all reality, your laying there quietly, as the mattress gently, yet distinctly begins to bounce slightly, then more and more rapidly until he finally gets it done or until you kindly ask if he would like some help.

I get secretly turned on when my boyfriend plays Jack-In-The-Bed.

Snack-jacked

When friends, family, etc. come to visit and eat all your snacks.

My damn brother came over last night and snack-jacked all my chips.

Jack

Jack is charismatic and doesn't care about being a cheater, full of lies and deceit. Massive arsehole with an even bigger head. Stay away from boys called jack.

‘Oh god he was such an arsehole a pretentious arsehole... what was his name?’
‘ with a attitude like that probably a jack’

Jack

A british jackass that annoys the fuck out of others, also known as Anon, will most likely lurk underneath your bed requesting to play video games

"That guy is such a Jack, look at him,"
"Oh yeah, he called me his m8 one day"
"he called me a faggot"
