Two people who are in love, but not currently in a relationship. They may choose to continue to make out, but they're not technically together.
Moronica: I thought Alec and Zoe broke up, but I still hear them say 'I love you' to each other and they make out aaaaall the time.

Steven: Oh they did break up, they're just lovebros.
