A/N: My sister really likes "Mean girls", so she tends to say the quote every Wednesday. For a long time, I was Dean (not understanding it).
Disclaimer: I do not own Supernatural, Mean girls, or a pink shirt.
Sam had taken a break one night while Dean went off to have a few drinks at a bar.
The older Winchester had come home the next morning, drunk, and stumbled to one of the hotel twin beds and passed out.
The next morning, he was hung-over and didn't really notice when his brother said odd things: commenting on the watch Dean always wore around his watch, and saying that Dean was acting like an animal. He just figured that his brother was annoyed at him for getting drunk and leaving him alone in the hotel room.
The next week, they had finished another case and had spent the night at another hotel. They were getting ready to leave that morning.
Since Dean had taken the first shower, he was already packed and ready to go by the time the shower in the tiny bathroom had shut off.
When Sam came out of the bathroom, however, he was startled to find that his younger brother was not wearing one of the plaid shirts that were almost a part of the Winchesters at this point.
Rather, Sam was wearing a bright pink top.
"Uh, what the Hell is that?" he asked, standing up.
"What is what?" Sam asked, pretending to be confused, although he knew exactly what his brother was asking about.
"The freaking pink, dude!"
Sam shifted awkwardly, stuffing his dirty clothes into a duffle bag. "Uh, well... it's a pink shirt."
"No duh! But why the Hell are you wearing it?"
Sam shrugged. "On Wednesdays, we wear pink."
The older Winchester gave him an incredulous look. "No, we don't."
"Well, we're supposed to."
Dean scrunched his face up in confusion. "Where the Hell are you getting this from?"
Sam blushed, turning away. He muttered something, too low to be heard
"What?!" asked Dean.
Sam sighed. "Mean Girls."
"What do you mean, mean girls? Did you get beat up by a stripper or something? Do you owe a girl money and they're making you wear pink as blackmail? What?"
Sam shook his head. "The other week, when you went to the bar, I stayed in and watched a movie called "Mean Girls." In it, they wear pink on Wednesdays."
Dean nodded. "Oh, so this is another chick flick."
Sam rolled his eyes. "Come on, Dean. I like it. I let you like what you want- no matter how disturbing that can be at times." He gave his brother a pointed look. "So why won't you let me like my own things?"
Dean sighed. "Whatever." He grabbed his bags and walked out of the room. "Like whatever you like, Sally."
Sam groaned, putting together his own things. He walked out of the hotel room, shouting "Fine, but you can't talk to me until you get a pink shirt."
