The Chub-Shake
The official Chubster greeting has two versions:

1. Low-key
For occasions when stealth and sneakiness are required.

• Shake hand as usual but use thumb to press the piece of flesh between thumb and forefinger
• Whisper the first part of the Chubster Call to each other - chub-chub-chub-chub - whilst maintaining eye contact

2. Full-on
For every other situation.

• Stand opposite your Shakee and hold hands aloft
• Smack hands together as hard as possible, whilst yelling "Ooowww! Ooowww! Ooowww! Ooowww!"
• After two or three seconds of hand-smacking, grab your Shakee's spare tyre and shake vigorously whist shouting "Chuuub!" triumphantly
