A person with a compulsive desire to steal things.

Many Kleptos steal things from work.
Not many people knew it, but Adam was a Klepto. He bragged about stealing laptops, hard drives, memory, tape drives, blank CDs, tapes, keyboards, mice, you name it.

– Anything he could fit into his oversized Microsoft bag would end up in his basement…

I lended my pencil to my friend, RJ, but she never gave it back and when I asked about it, she said that she had lost it even though she was using it. That fruitloop dingus is such a klepto!!!

One who, despite not having any other klepto tendencies, will habitually pocket other people's cigarette lighters. Typically this unconscious act of thievery happens after a weed session. The number one reason a BIC lighter will often pass through 20 other owners before it's spent.

Better keep an eye out next time. Now I gotta walk to the fucking store in the rain.

On Fridays, we steal things… Klepto Fridays can be defined as the last day of the work week during which folks are encouraged to filch items from businesses and public places to be shown off to friends and kept as trophies.
