shake the tail 

When you've farted in a building while on the move and you take an indirect route to your destination in order to shake off the smell, disperse it and make it more difficult for those around you to track the source of the fart.

"Hey, what took you so long?"

"Sorry buddy, I had a huge curry last night, had to shake the tail, so I zig-zagged around the halls for 5 minutes"

But how often does the lamb shake its tail?! 

What an anxious/impatient youngster would logically want to know in instances when his parent promises a certain action/food/relief/entertainment "in two shakes of a lamb's tail".

Cranky child: "Are we there yet?!"
Parent driving (cheerfully): "Oh, no worries --- we'll be there in two shakes of a lamb's tail!"
Cranky child: "But how often does the lamb shake its tail?! Oh, sure --- a NORMAL AND ALERT lamb probably "flutters its little stumpy thing" quite regularly, but if the lamb is asleep or not feeling chipper, its behind-flipper might not move much at all, and so it might take HOURS for it to jiggle even ONCE, let alone TWICE!"

Tugged on the tail of a snake 

Line used from the movie end of watch. It basically means “ you just messed with/pissed off the wrong guy, and he’s gonna make you pay.

You and your homeboy need to power down, cause you just tugged on the tail of a snake, and he’s gonna turn around and bite you back.
