Otp means one true pairing, but let's be honest. We all have more than one! When your otp does something even remotely cute, your heart practically poops it's pants. You may also throw yourself off of a building and/or sell your soul to satan so you won't feel any more pain.
Person One: Destiel was soooo cute last night!
Person Two: I know they're my OTP! I almost threw myself out the window but instead I just ate my feelings again.
