Sleeper McSleepington

A person who loves sleeping. He/She would rather sleep than do anything else in this world. They also have no problem falling a sleep and can sleep up to 14 hours. Insomniacs are often jealous of these type of people.

Ryan the insomniac can't fall asleep if his life depended on it, while Sleeper McSleepington started snoring while talking on the phone. Sleeper woke up the next day with the phone off the hook.

Sleeper cell

When a buddy is hanging with you and starts talking to a girl, then throws you under the bus to try and get some from her. He turns his back on his boys to further the chase.

Jake just went sleeper cell on me and Jethro at the bar to get after the married chick.

Sleeper Build

A PC with an external case (if desktop) or shell (if laptop) that appears incredibly outdated, but when opened, contains modern parts, and when turned on, runs a modern operating system.

Some guy broke into my house last night, but luckily he never took my PC.
Oh yeah, that's probably because you have a sleeper build.
