Sideline Simping

When a girl you like is in a relationship, so you stay friends until she is available. That is when you tag in and shoot your shot.

Her: "We have been fighting recently so I don't know, we might break up."

You: "I hope you can work it out. Just be careful, Celtic is totally sideline simping."
