Aut disce aut discede - Learn or vanish
Cogito ergo doleo - I think, therefore I’m in pain.
Cogito sumere potum alterum - I think, therefore I’ll be having another drink. (must show both Snape and drink :))
Fronti nulla fides - appearances are deceiving (ugly Snapey)
Hic puer est stultissimus omnium! - this boy is the dumbest of them all!
Hunc tu cavetto - beware this man (scary Snapey)
Me oportet propter praeceptum te nocere - I'm going to have to hurt you on principle
Oderint dum metuant - Let them hate if they also fear
and my personal favorite: Qvae nocent docent - What hurts also teaches
If anyone can help me out, I'll be very grateful!
