When a person becomes extremely close friends with a new acquaintance at a scarily rapid pace, and is unable to speak or think (publicly or privately) of anything other than this new BFF, or spend time with anyone but this new person. This lasts for a period of up to 3 weeks, when the superfriendship dies, resulting in a 1 to 2 week period of drama, until the superfriender finds their next mark.
What's Cara doing doing tonight? Oh she just superfriended an indian chick at her new job... she will be unavailable for a few weeks.
You usually find out your SUPER FRIENDS with someone when you are both extremely blazed or wasted. This condition of being SUPER FRIENDS does not end with the high however, and will remain beyond the death of both SUPER FRIENDS.
