Billy
'Billy' is a developed verbal-to-physical meme on TST.
This comes from two particular members who came across a pigeon walking about, being annoying as they usually are. Member no.1 coaxed the pigeon to come near him saying in a creepy voice "Heeeere Billy Billy Billy" and Member no.2 proceeded to do the same, this ranges between 'WTF' and 'zOMG hilarity!' currently.
Not long after, Member no.2 took it a little too far and proceeded to do what is now known as the 'Billy Billy Billy Billy EXERCISE'. See below.
Billy Billy Billy Billy EXERCISE:
1. Place your arms a little higher than your body.
2. Space out your legs and feet.
3. Make your arms go backwards and forwards at a formidable pace.
4. Hop forwards a couple of times.
5. Try the above two together.
BILLY BILLY BILLY BILLY.
