A "couple" who can been seen making out at parties together, hanging out at school/each other houses, going to the movies, etc. BUT they insist they aren't dating, mostly because they want to bang other people. Hence why they're officially unofficial.
Dude 1: Whoa, check it out. Matt and Allie are making out again!
Dude 2: Yeah man, they've been officially unofficial for, like, 3 years.

Someone who you never really verbally had the chance to break up with (probably due to lack to technology or secrecy) where distance and/or random event caused an unexpected split.
"My parents decided to move out of the country short and notice. I wanted to call and tell my girlfriend but the phone had already been disconnected. I never got the chance to officially break up with her and didn't really want to. So technically she's my unofficial ex. I found her on Facebook....she's now married with 3 kids."
