Yawn Boner 

Sometimes called "Yoner", is when one gets an erection from excessive yawning. They will often come about with no warning and are usually harder than a normal erection. They will usually happen in the morning, often during class or at work.

hippo's yawn 

a simile for a particularly large vagina, named so because it resembles a hippo yawning. minus the big teeth a hippo possesses of course. that would just be weird.

a hippo's yawn can usually be found attached to a slosher or perhaps a lady that has given birth to twins with heads like south park's mr mackey.

trevor : how'd it go with that slag last night then?
pete : mate, she had a minge like a hippo's yawn
trevor : that bad huh?
pete : seriously, it was like stirring a bucket of wallpaper paste with a pencil
