R.T.B. (Relationship Transmitted Baggage)

When the baggage (i.e. commitment issues) from a previous relationship causes a person to break up with their new partner, and as a result, that new partner gains the baggage of the dumper, which causes problems in the new partners future relationships. Similar to an S.T.D., except mental rather than physical.

"Dexter, why don't you just date that cute girl from school that texts you all the time?" "I can't! Catherine gave me R.T.B. (Relationship Transmitted Baggage), and ever since I have serious commitment issues."

Nonsense

Something that is irrelevant, unimportant for details in a story, or something that conflicts with your schedule, ie a reason for why a party member is absent; respectfully, with no insult to the actual activity the absent is attending. A fun way of saying “extraneous.”

“Where’s John?”

“Oh he’s up to some nonsense, school related.”

“So I was working a double, and he hits me with this nonsense I gotta pickup on the way home.

La La Landed

When a couple breaks up because it is "right person, wrong time", with the expectation of getting back together a year or more later, but when they meet again one of them has moved on.

yo, my homie Ryan got la la landed as fuck. Casey even said she'd be willing to try again after her senior year was over.
