April 18 is the national day to send pictures of yourself in only underwear to your boyfriend- especially if his initials are ALM.

A one night stand that acts like your significant other, rather than a hit it and quit it.

Duties include, holding hands, sweet nothings, kisses on the cheek and meeting friends and family all on “first” date.

“One night boyfriend” is often followed by full hungover / drunk next day then to never hang out again.
My binge date last night turned into total one night boyfriend yesterday. We met up at Happy hour then he came to friends bday dinner and chilled all night long, had amazing sex then went to brunch with his friends. Fast forwards never spoke again

A boy with whom you share a close emotional bond; communication is largely limited to over the phone. You text all the time but for some reason can’t or don’t meet up. May or may not ever become your real boyfriend.
From Schitt’$ Creek episode 5x05 (Housewarming)

(At Patrick’s housewarming party)
David (to Stevie; indignantly): Where’s your phone boyfriend?
Stevie (Exasperated): He’s...on my phone?
