When a chick looks good from far away or at a glance, but then the sad reality becomes clear that they are as ugly as the north-bound end of a south-bound horse when approached or when a better view is available. Also, cute in theory
Example 1
Dude: Bro, did you get a good look at that hottie that just passed us? I missed her.

Bro: Yeah dude, don't worry about it, shes only theoretically cute, nothin to worry about.

Example 2
Bro: Holy crap dude, you didn't tell me you had a sexy-ass neighbour!

Dude: Yeah cus she's just cute in theory

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed
I got a call from X the other night. She had an extra ticket to a concert she bought for a friend, but they couldn’t make it so she called me to ask if I wanted to go because I am her Second String Friend.
