sedultress 

Sexy female, with one objective - FIND AND DESTROY (a taken man)!

She wants nothing but to use and abuse, disposible like a rubber after the fun has been knocked out of it. She certainly doesn't want to use "it" again. And the best part? She wants him coz he's not for sale ;)

X: "He's hot"
Y: "err he's also taken...? Off limits."
X: "Wanna bet?" (wry smile)

1 hour later returns with a bed head and his tie in her hand
Y: "You are some sedultress"

quod potero sedulo

a high school called orange high school uses the quote quod potero sedulo thinking that it means "whatever i do i do to the best of my abilities" when in fact it actually means be able to pay. however they are that clueless about it they just say that the person who said that is wrong. it's also hypocritical considering that school funding is shit like you would expect.

you: hey? remember when we searched up that stupid quote from our school and found out what it actually meant?

person 2: the quod potero sedulo one?

me: yeah, that one.

person 2: oh yeah, that was stupid.
