Too Big to Fail

A turd, that by itself, is large enough to clog the toilet without the use of paper, possibly needing to be broken up with plunger etc.

"I took a mean dump this morning. I had to poke at it with a plunger until it went down. That shit was just too big to fail"

big boy shoes

Nice, expensive, larger than usual rims for your car or truck. Such as spinners or Daytons.

big day out

The biggest, and best music festival in Australia. It tours Australia and New Zealand every year, and has some of the best music acts around. This year was the best ive been to, with The Killers, My Chemical Romance, Tool, Jet, Muse, Evermore, Eskimo Joe, The Presets, Lily Allen, Hot Chip and Sick Puppies.
The day runs from 10am till late, and features about 5 stages, so theres always someone good to listen to.
Plus, theres awesome rides and stuff if you get tired of the mosh environment!
Best day of the year!

I listened to The Killers from the top of the ferris wheel at Big day out '07. It was mad!

Big Shades Theory

The theory that proves that 96% of all women that wear big 60's style sunglasses trying to look like M.K Olsen or Nicole Richie; are in fact ugly ass horse faces. These woman wear these " vintage knockoff" glasses in order to cover up the hidden horse face. As for the remaining percent, 3% are the women who are actually stunningly gorgeous and their glasses are either Fendi or Dior, and the remaining 1% are the fag ass dudes wearing purple/yellow scarves and grey cheap mondays who were never cool in highschool and still aren't cool.

1. dave-"yoh bro, check out that broad ore' there with the huge shades!"
shad- " no man, think about the Big Shades Theory that Kent taught us, she is totally a horse face."

2. dave- " yoh bro, check out that dude with the big shades. what a stunner douche."
steve- " yeah, what a douche, check out his sweet tapered cheap mondays though, never seen those before..."
