According to Know Your Meme:
Sh*t People Say is a series of parody videos exploring social and gender stereotypes using the phrasal template “ Sh*t X says.” The videos were inspired by a single topic blog and web series titled “ Sh*t Girls Say,” showcasing various cliches and verbal mannerisms that are commonly associated with teenage girls and young women . . .
With that in mind, the above video from Lambda Legal is called 'Sh*t Homophobic People Say.' And boy do I wish it were a parody.
