cranial expansion

The feeling of immense pressure on the inside of your skull the morning after a party.

Guy: "Holy shit, this is the worst cranial expansion I've ever had. Where the hell am I?"

Girl: " Yeah, you were pretty wasted last night, you asked me if I wanted to 'take it to the next level'. I laughed right onto the floor. That Hyundai guy who lives here wants to know where we are, too."

Hair extensions

Almost always 100% human hair that you can attach to your hair by either clips, glue, or weaving it in to make your hair look naturally long. Sometimes you can buy them synthetic (fake) but it looks more natural real. You will see a lot of famous people with them in for example Paris Hilton. Extensions are in for punk/emo/scene girls for example Kiki kannibal.

"OMG my hair is taking forever to grow, I think I'm just going to buy some hair extensions"

"Did you see Kiki Kannibal's hair extensions? they look bad ass."

The quality of tape measure that makes it fun to play with, especially metallic tape measure.

Stew's extensive new tape measure kept him up all night, seeing how far he could extend the line before it went limp.
