a leonowens
When you and your boy are fucking a girl but you both in the pussy at the same time. Even though your two dicks are touching it's not gay because it's happening inside a vagina.
Me and my buddy gave a girl a leonowens last night... I can't believe we both fit inside her pussy like that!
Reverse Leonowens
When your girl is bi and convinces another chick to bang you both at the same time.
Dude I went to a party last night and my girl got this chick to come home with us and they gave me a reverse leonowens!
