Indian headshake 

A shake of the head from left to right in a 45 degree angle which usually means a "Maybe", i.e. Neither a Yes nor a No.

Typically used in India and nearby regions to say "yes" out of politeness or duress, but really meaning a "maybe".

1. There are times when the Indian headshake can be useful. Like when your girlfriend or wife asks you whether she has gained weight.

2. Seagull Manager: Can you get this presentation done by this evening...

Junior Employee (fearing for his job): <does the Indian headshake> I think so

Seagull Manager: Great, I'll expect it in my email by 4pm.

Indian Handshake 

A handshake, characterized by an utter lack of firmness in the grip, and often, a sweaty palm, giving the receiver a creepy and unpleasant feeling. Commonly given by men from India, hence the name.

Alice: Who’s that man you were talking to this morning?
Bob: Hmm… oh, right. Rajesh something or other. He gave me the Indian Handshake.
Alice: Eeww!
