being new here I literally have no idea who these Steeming Young Lads are or why they are together.

1st Guess:

Guy in middle jumped in as he is the bartender, just for a photo shoot from a famous asian guy and some awesome older guy that were just talking bout business. Hence why guy in middle has a slight smile, guy on left does not care and guy on right is always smirking like the beautiful bastard he is.

2nd Guess:

Guy on left is pissed cause the camera guy said cheese. Guy in middle is smiling cuz we know he likes cheese. Guy on right is like fuck cheese, look at this Kebab.

3rd Guess:

This is a family picture. Yes. Guy on right is the Patriarch of the family. The guy in the middle is his son, maybe he wanted him, maybe he didn't. Who is to say other than the guy on the right. So it could be his legitimate son, which I doubt, their smiles do not match. But maybe middle guy takes after his mother. So he could be married in. Smirk from right guy makes sense, if he likes him. Otherwise just a son-in-law he sometimes cares about, most of the time does not. Now we get the guy on the left. He is for sure married in, unless some spontaneous nature evolution happened. My guess at best, boyfriend of either the middle guys side of the family or the right guys side of the family. Either way he knows what is up and does not approve of this picture or this message.
