Learn English – Can “Yo” be used to end a conversation

slang

I understand "yo" is meant to be used as hello or for emphasizing something. But lets say in a situation where I am texting with someone and at the end of that conversation using "yo" instead of "ok" is correct. Lets take this text for instance.

Me : Yo

Roommate : sup

Me: The internet ain't working.

Roommate : Yeah I got the email. I will recharge it later.

Me: Thanks dude.

Roommate : Yo.

In this situation, the roommate is using "yo" for saying "yeah kool, bye".

Can yo be used like that or its just wrong to use "yo" to end a conversation even when texting?

PS: I am sorry If this question has already been asked.

Best Answer

Yes, you can use it at the end of a conversation. According to Wikipedia:

Yo is an English slang interjection,[1] commonly associated with American English. It was popularized by the Italian-American community in Philadelphia, Pennsylvania in the 1940s.[2]

Although often used as a greeting, yo may come at the end of a sentence, often to direct focus onto a particular individual or group or to gain the attention of another individual or group. It may specify that a certain statement that had been uttered is more important, or may just be an "attention grabber".
