"REMUS! GUESS WHAT I LEARNT TODAY?" Squealed James as he bounced up to his friend.

"What?" Said Remus, his tone flat, but still full of concern for what his virgin ears were about to hear.

"When someone is" his voice dropped into a near whisper. "sexually attracted to you. Their pupils dilate."

"Lovely." Said Remus, who had overdosed on his sarcasm vitamins this morning.

"What's lovely?" Asked Sirius as he suddenly appeared behind James.

"James says that when you're sexually attracted to someone, your pupils dilate." Explained Remus. Making Sirius jump, as though he had no idea previously that Remus was straight in front of him, he looked at Remus directly in the eye and-

Remus choked on his own breath when he saw Sirius's pupils enlarge at a smooth pace.

James was oblivious to the situation.

"Hey, Lily, have I got something in my eye?" He asked coolly as he crouched on the ground, so he was eye to eye with Lily, who was reading the paper on the sofa.

"I-I can't see anything Potter, apart from your proportionally disfigured head obstructing my view." She said in a monotone.

Normally, James's ego would have taken a major blow after that and would have taken at least thirty seconds to recover, but he didn't notice what Lily had said at all.

With an enormously large grin on his face, matching his 'proportionally disfigured head' he waltzed over to where Remus and Sirius (Remus with a slight frown on his face from what he had just learnt, it was a worrying frown. And Sirius was fiddling with his wand.)

"LILY EVANS LIKES ME." James looked like a parent that had just seen his child for the first time. "LILY EVANS LIKES ME, THE ARROGANT PRICK."

"That's nice." Muttered Remus, his face in fear.

Game: find all your friends and look at them in the eye really intensely. Have fun! Also, for extra lols, hold any ones hand in casual conversation, just to make it delightfully awkward. One point for each pupil pair dictated and/or hands held. Play with your bro's and wingmen and see who can be the first to five or ten points!

Points lost if you're the one whose pupils dilate. You can try and brush it off with saying you were thinking about James Potter in a mankini or something (preferably something better than a mankini, like his birthday suit or something, otherwise you will be known as the chick with the kink for mankini's, no one wants that.). I have no idea what you guys like, get creative. Like I said, you can try and brush it off, but if your pupils dilate, it's either getting dark or you are completely and utterly screwed.
