tumblring 

The act of being on tumblr for hours and hours.

I was tumblring so hard last night I forgot to sleep but it's okay because I dipdyed my hair and got an american flag tank and combat boots, I'm a hipster now!

tumblring 

Massively overstating how entertained you are in the form of either dying, crying, or noting the point in the universe where your sides reside.

"oh my god i'm dying from laughter" "no you're not, fucking liar." "no dude, i'm serial. My sides are this ( |<-------------------->| ) far apart!" "stop tumblring, bro."

Tumblring 

Pretending that one's eccentricities and moral shortcomings aren't personal and that every unacceptance of them is bigotry.
