You might want to avoid celebrating your birthday in India! Luckily, as I am born in the spring, I won’t have to celebrate mine here...
On the campus, birthday rituals include:
-Cake smashed in the face
-Cold water poured over the head
-Having to perform silly sexy dances
-Being kicked in the ass!
Regarding the latter, the birthday boy* is held up in the air by his hands/legs by his friends and kicked in the butt. The number of bumps is supposed to equal the age of the person but the kicks usually don’t stop when that number is reached. And the kicking is quite brutal!
The birthday bump tradition is widespread in India (not IIMB specific) but is not usually followed in presence of families.
*Girls are not spared but the kicking is gentler as it is done by girls only.
