How to become a caver?

[Baazalung]

Q: What do I have to do to become a caver?
A: You have to drink, to stink, to fart and to burp.

Taken from the Romanian Caving Mythology
Drink-it implies alcohol
stink- implies smelly feet and armpits, result of intense caving
fart- i guess you know what that means :)
burp- same thing here
