"Too hot, too hot!"
From the play The Winter's Tale, spoken by the king, Leontes, when he (wrongly) suspects that his wife is having an affair. Used multiple times a day in reference to a variety of things, including the temperature on the Tube, as well as a euphemism for possibly awkward conversations during class about Shakespeare's romantic plot lines. Our everyday conversations became increasingly peppered with what we called "nerdy but great" Shakespeare references. Other popular ones: "kissing with inside lip" (also from The Winter's Tale), "Go to! Go to!" (from Romeo and Juliet and others, used in the sense of "let's go!") and, "Look, it's the pastoral space!" (a classroom term, used in reference to sheep and the pastoral countryside that Shakespeare wrote about).

"When I'm applauding at the end of Hamlet, I really feel like I'm applauding myself."
Quoting Professor Post, in reference to the lengthy nature of this play. However, our production thankfully was cut to three and half hours, and Jude Law's acting made it quite entertaining for such a depressing play (also, he's attractive, but from our seats in the nosebleed section we could not have known this, so my assessment of his acting is less biased than one might think).

"What does Rick Steves say?"
Quoting me and my roommate, whenever we need answers about where to go, what places are worth paying for, when they're open, etc. Rick Steves writes amazing travel guides, and I was exceedingly grateful that my roommate brought one! We began to refer to it as "he" rather than "the guidebook" because we love Rick's advice and quirky commentary so much. We also wanted to know if he has any sons, because if so, we'd like to date/marry them.

"Will power!"
Quoting various students, including myself, who purchased shirts in Stratford that say "Will power" all over them and have some of his plays, with little illustrations, on the front. I plan to wear mine when I have writer's block or want to procrastinate on homework; the idea is that Will's literary genius will inspire and motivate me to write well ... hopefully "will power" will come through for me from here on out! Who wouldn't want to write the way that Shakespeare did?
