I especially love when teen dramas reference each other, because a) it's cute, and b) it suggests that the characters have seen other teen dramas, which brings up a whole slew of implications.
For example, I love when Haley references Dawson's Creek on One Tree Hill, both because it pays homage to the Dawson Creek's influence on One Tree Hill AND because Chad Michael Murray also appeared on both shows.
I also love when Spencer refers to Sara as the new "Big Bad" on Pretty Little Liars, because I love any and all references to Buffy the Vampire Slayer. The influence!!
I also think it's cute when Damon calls Bonnie "the teenage witch" in The Vampire Diaries. I like to think that Bonnie took some inspiration from Sabrina.
Sometimes the references happen because the show is a spinoff of another show or exists in the same universe — I loved when The Chilling Adventures of Sabrina referenced Riverdale because it's just so wacky to me that those shows exist only towns apart.
