emptyquote 

Quoting a text someone else posted without adding anything of your own. Used when the person quoted has summed up exactly how you feel, and you have nothing to add.

"Ditto"

It can also be used to make a post permanent, if the person said something really stupid and you want to make sure he/she doesn't want to edit it away or delete it after thinking it over, forcing them to live it down.

User1 : I'm so glad this semester is over!

User2 : User1 : I'm so glad this semester is over!

In this example, instead of saying 'I agree' he employs the emptyquote

emphaquote 

to use quotations to stress certain words of a phrase to extract the most humor from it and not necessarily be logical.

Yo i really liked that 2pac emphaquote you "dropped" the other day: i see no "changes" i wake up in the "morning" and i ask myself, is life worth livin or should i "blast" myself? im tired of bein poor and even "worse" im black, my stomach hurts and im lookin for a "purse" to snatch.

yeah i have to get back to "work" tomorrow and "babysit" my brother for a while. I'll probably take "him" to see harry potter.
