Mahima

Someone who forgets to reply to your texts and respond to your calls.
Someone who has a sudden realization every two or three months that they have friends, and they need to catch up.

Ironically, they're both - great at communication and a communication sloth.

Person: Did you just pull off a Mahima on me?!
Person: Sometime being such a Mahima is going to come back to bite you in your behind.
