land up with (someone or something)
1. To be with someone, often by default. It seems that we've landed up with the most boring tour guide on the planet. He's seriously putting me to sleep. If you don't start dating more serious guys, you're going to land up with a doofus.
2. To possess something at the end or as a result of something else. We landed up with nothing because the yard sale was a bust. I landed up with a ticket to the concert because one of Nicole's friends couldn't go at the last minute.
