We're gonna go out on a limb here and guess this is not your grandmother...

And yet, aside from all-caps comments and interrogations about “that person in your picture” and if/when you're marrying them, grandparents have found a new way to embarrass themselves on Facebook. Thanks to the auto-suggestion tool, grandmas all over the world are mistakenly tagging themselves as the one, the only Grandmaster Flash. As soon as granny starts typing “grandm,” Facebook types in the rest.

It’s become so common that there’s an entire Tumblr dedicated to it, filled with hilarious examples like these:

You can say that again! Consider this a public service announcement: Tell your grandmas that, although it’s admirable that they want to flaunt their “hipness” by being on the 'Book, they should check twice before signing their name. Or don’t tell them, if you just want to keep the hilarity going. No judgment here.

And yes, Grandmaster Flash himself has seen the hilarious trend -- and acknowledged it in the best way possible:

It's true, I get a lot of posts from Grandmas. Hilarious - Respect Grandmas & Grandpas of the world, this is Hip Hop http://t.co/UICL30a6H6
