Dragon's tail 

A dragon's tail is a kind of whip used for BDSM consisting of a long, stiff handle and a single lash usually made from leather or suede. The lash is a triangular shape with the wide end partially wrapped in a cylindrical shape protruding from the end of the handle. The thin pointed end of the triangle makes contact with the recipient’s skin upon striking.

She whipped me good last night with that new Dragon's Tail she has.

Turtle’s Tail 

The opposite of a turtle’s head. Having made it to the lavatory, dropped a big one and flushed. The turtle’s tail can be found lurking on the consumer side of the U bend.

Dad: Bloody hell! Who’s left this turtle’s tail in ‘ere!

sucking the cat's tail 

Slang for performing fellatio. It means to suck on a man's penis. This, if done properly, often results in a hoarse throat or minor irritation to the larynx.

Jane: Oh, my throat is so sore!

Alex: You been sucking the cat's tail again?

Tiger's Tail 

A really fat and long penis that is so good, it feels like your being whipped by one.

1. Jenee received a text message from Jerome. It said "Hey baby I'll be over tonight, hope you're ready to tame the Tiger's Tail." Her response was..."Of course baby, I'll cum meet you in the stairway at 7:30 sexy."

rabbit's tail 

The completely unexpected - but most welcomed! - brief moment of witnessing a sneaky glimpse of a girl's white panties e.g. when exiting a car in a short skirt.

"Keith, Keith, did you just clock that bitch's rabbit's tail?!"

Barney's Tail 

When a penis is sucked so hard, the head, the shaft, and scrotum turn a dark purple color.

"I'm still suffering from the Barney's Tail my mother gave to me."
