Black Friday

'Black Friday' is known as the official start to the holiday shopping season. It is the day after Thanksgiving. Many stores open very early, at midnight or 5 a.m., and have huge mark-downs on popular items.

It is called 'black' because in accounting, that means that the store has profits, as opposed to red, which would mean debt.

Example:
-I heard Toys-R-Us is having a huge sale on Black Friday! I can't wait to get my grandson a bouncy horse.
-We'd better get there early so they don't sell out! I bet it'll be packed!

Yo!

"Yo!" is a very informal, familiar greeting, kind of like "Hey!" It can be used when you don't know or can't remember someone's name and want to get their attention. Another possible use is as a shortened form of "your." It originated in African American Vernacular English (AAVE), but has now been adopted by speakers of all ethnicities. It is interesting to note that "yo" also means "I" in Spanish, a language widely spoken in the U.S., but in American English it doesn't mean that, nor is it related.

Examples:
-Yo, come back here!

-Get to work, yo!

-Yo mamma!


True story:
I'm white. Sometimes when I call my dad on the phone and he sees it's me on the caller ID, he answers, "Yo!"
