masters towel

When you need to go #2 at Twin Lakes and resort to desperate measures. Keeping said towel in your bag while covering the odor with Febreze adds to the party.

Man, I had to pull out the masters towel on #7. I didn't even wash it.

Mattress Bra

A bra with so much padding/push up that the extra volume alone is larger than the size of someone's boobs. Mattress bras are usually extremely thick and uncomfortable to wear.

"Dude, this chick I took home last night had MASSIVE TITS. I was so excited until she took off her mattress bra and she went from a DD to a B at best..."
