McHappiness

A double cheeseburger (plain, just cheese + meat) with an entire Mcchicken (buns, lettuce, mayo, and all) sandwiched in between.

John Smith bought a (plain) double cheeseburger and a mcchicken and is combining them into a Mchappiness. What a lucky fuck. And all for only $2.12!

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.
