I love this idea so i just have to continue it.

mad – an excessively large amount.
e.g. I got mad love for you. or Whoa I ate mad french fries today.

I hate his/her/your/its life – used in contempt for a person you just really can’t stand.
e.g. Simon Cowell is so annoying. I hate his life.

chea – because you’re just too cool to say yea anymore
e.g. “We still on for the movies tomorrow? “Cheaaa.”

Play it off – said to save face after an embarrassing event
e.g You just tripped. Straighten up and say “Play it off, play it off,” and keep walking.

tight – to be really mad
e.g. “I can’t believe I failed another math test. My mom is gonna be so tight when she she’s this.”

So’s your face! – must be said with enthusiasm. When used at the right moment can be an awesome comeback, but otherwise usually makes no sense
e.g. “Your dress is so ugly!” “So’s your face!” or “I hate cheese.” “So’s your face!”

preggers – pregnant
e.g. “Didn’t you hear? Jamie Lynn is preggers!”
