MLISC 

"My Life Is Super Cool," an abbreviation used frequently on MLIA to describe comments and responses to Google Mystery "ninja missions." Most of these posts are not, in fact, super cool.

"Today, I was on Mystery Google. Someone challenged me to do a ninja roll into the next room and roar like a dinosaur. I did it, and I've never seen my brother laugh so hard. Thank you, mystery person. MLISC."

~ it speaks through a relatively gaping hole on its head which is surrounded by giant wet lips.

~ When a miscavigina’s pink hot rage is in bloom, shrieking screams are expelled from between its sopping wet labia lip tissue; exerting a sound only comparable to that of a supersonic queef.

~ Legend has it that the puny presence of a miscavigina is the byproduct of Stunted Growth Syndrome (SGS); effects undergone amid a curtailed puberty.

Word Origin and History for miscavigina

n. 1680s, from the Latin ‘vagina’

The most famous miscavigina of the 20th and 21st centuries is—one David Miscavigina, for whom the term was originally coined. Miscavigina is successor to Scientology’s sci-fi author, L. Ron Hubbard, aka ‘L. Ron Gingivitis’

David Miscavigina has faced much controversy in recent history as result of his ongoing ties to the notorious brick road gang—‘The Lollipop Guild’. Miscavigina vehemently argues against accusations that ‘The Guild’ (as referenced by Miscavigina) is indeed a gang; he stresses that The Lollipop Guild is not a gang but a “club”. Still, Miscavigina remains an active member in this “club”, as part of its NORTHWITCH chapter.

JOHN: Why's it getting so pink in the face? And sweaty?

JANE: Uhh, I don't think that's sweat. Whatever it is, it looks pissed.

JOHN: Wait...I've read about these. That's a miscavigina!

{The Sound of a thunderous queef radiates through city streets, sending chills up the spines of all there to observe it}

JANE: Aww...he's so cute! He's almost like a real person.

JOHN: Yeah. I wish he wouldn't spit so much while he's screaming though.

JANE: There it goes, it's running into the crowd. Now we'll never find it among normal size folk.

JOHN: Yep. It's Going Clear outta sight.
