I just thought of something: you and I are part penguin and part llama. However, you can only have one patronus. Which one of us would have which patronus?? Guess we'll have to expecto patronum it up when you get home.

erecto patronum 

A spell cast by an attractive female on a male or group of males. As she walks into the room, the spell is cast and all males who make eye contact with the woman receive instant erections.
Side Note: The spell can be cast without the attractive female's knowing but by simply dressing provocatively.

Ex: As the gorgeous model walked into the room, erecto patronum was cast and all of the male photographers received boners visibly seen protruding through their pants.
