Jackintosh

A nickname for the Atari ST computer, after Atari Corporation's then-CEO Jack Tramiel. A reference to it being a cheaper competitor to the Apple Macintosh.

My parents were poor in the 80s and so they bought a Jackintosh for me to do homework on.

Jackinho

A guy who thinks putting 'inho' on the end of his name is cool. In reality, it isn't. Jackinho is someone who isn't very popular and doesn't have any friends and really struggles to adapt to the realities of society and is often friendzoned by girls who are convinced he is gay. This is a guy would often write very poor poems about his emotions just to gain some form of attention from people he doesn't know. He is very much life's own perfect loser.

Brooks: 'Do you know that Jack kid?''

Akers: 'Jackinho, the poem writing loser. Yeah I know of him, everyone thinks he's a muppet'
