The most Indian thing ever

Chai.
Chai is the morning drink for most of the Indians and it may instigate headache to many if they don't drink it ;)

Bhangra in weddings.
“Shaadi vaala nagin dance” is the best part in typical indian weddings.

Wishing Namaste .
Namaste in the form of “Radhe Radhe" or “ram ram” etc is a traditional thing for Indians.

Roadside stalls .
These stalls are just amazing after tiring long drives .

Using toothpaste till the last ounce of paste is extracted from tube.
“Full paisa vasul” :P

Free food.
Free food for all in temples on a daily basis (in some temples) are just the saintly thing.
