lab partner 

When you're going out with someone but you're in that awkward stage where you are transitioning from best friends to boyfriend/girlfriend. You basically are afraid to even touch each other. Don't fret, soon you'll be making out and all of your other friends will yell at you for PDA.

Dude, you guys are so awkward

Don't worry, we're just being lab partners.
