Credit to emsd01 for she came up with this definition <3
They're called crack ships because they're a joke. You don't actually ship them rather for the shits and giggles.
Eg.
I love reading and making gay jokes about Tobirama and Madara(ems does too)
Update schedule: everyday unless I'm a lazy bitch
If theres a word your unsure of or want definition of just comment it ^^
