McSlap

!. To be slapped by a clown, usually (but not restricted to) of Ronald McDonald's appearance.

2. To be bitch slapped by a McDonald's employee.

3. To strike someone in order to steal their fast food meal.

1. I tried to give that clown over there a hug, but I guess he was in a bad mood. I got McSlapped!

2a. I didn't want fries with my meal, and the dude behind the counter McSlapped me! So much for "We love to see you smile, huh?"

2b.I swear to God, I'm going to McSlap that customer if he asks me one more time if I want the Happy Meal in his pants.

3. Person 1: "...So then I came into this clearing and saw a family eating some fast food at the Picnic Benches."
Person 2: "So what did you do?"
Person 1: "Well I was so hungry, I snuck up behind the guy, McSlapped him hard, and ran away with his Big Mac and Fries. It was so worth it."

Employee: That'll be $4.95. Drive around.

Customer: ...Where do I go?

Employee: .... *sigh*
