Heterobaiting
Showing hetero couples (John and Mary..) on TV shows (Sherlock...) to lure hetero people to them what, obviously, is false information 'cause the TV show is gay AF (And TJLC/Johnlock is OBVIOUSLY real and canon). Mofftiss, the creators of BBC Sherlock, we're the first ones to invent heterobaiting.
"OMG did you saw John and Mary's family photo with their baby? SO CUTE OMG THEY ARE SO IN LOVE AAA-"
"Don't be stupid! They are obviously heterobaiting. I mean, John doesn't like Mary, he likes Sherlock and johnlock is becoming canon in season 4, you silly!"
