Adacus 

An Adacus is a young man who is incapable of expressing his emotions. Adacuses also known as Adaci in plural form can have a range of skills but will never surprise you because they will use any chance they get to show off said skills. There aren’t only bad things to Adaci though they are extremely committed to things they set their minds to and are also above average in intelligence. All in all Adaci are good friends except when they get busy and accidentally ghost you.

“Some dude just told me he’s a sociopath”

“Oh he’s probably an Adacus”

Devil's Abacus 

When you are arguing with someone, but are a complete idiot and make it sound like the devil is playing with an old school counting device.

I agreed with her, but I just wanted to play the devil's abacus.

Atavus

Aliens on the TV show Earth Final Conflict. A throw back to before the Taelons and Jaridians diveraged as seperate species. They are humanoid looking but have laser claws that protrude out of their fingers which they stab into people's chests to suck the life force out of them. Atavus' are very evil and highly sexual creatures.

When Taelons are seperated from the commonality they devolve into Atavus.

abacus

A chinese counting machine. Now outdated, has been banished to preschools and daycare centers for childrens entertainment. Sometimes considered, in its most basic form, the first computer.

Consists of 5 horizontal bars, each holding a number of beads that slide back and forth.

The little girl pushed the beads on the abacus from one side to the other.
