The shards of poop that stick to your butthairs from a non juicy poop. These typically hurt if not removed at first wipe and not alot of gas is moving through the anal cavity.
I brought tears to my eyes by trying to remove a shitflake after two days of constipation.
Being shallow and pathetic and living your life at the lowest level of ball-sucking that even i think your a fag. Basically, if you suck at life and are a terrible human and are completely fake, you are shitcrank. Also if you are seriously annoying.
Example 1:
Emmy: "I hate that girl Janice, boy is she shitcrank like no other. Its like she has no personality of her own!"
Maggie: "Amen to that, sister!"

Example 2:
Isabelle: "like, omg i asked my mom ? she said its okay to go be a ditz and bug people ?"
The World: " I hate you, you shitcrank bitch."
