They would be two completely different things, given Dean wasn't from 'Earth' per say, maybe? It would be hard to explain, and Dean was definitely not the one to explain it. "Oh, okay! Well if Ritchie liked them, Dean would be sure to like them too!" It would be rather obvious that Dean had taken a liking to the young man, seeing as he was friendly.
"Oh, okay, so Ritchie mated with this Indian man!" There was absolutely no judgement in his voice, in fact he smiled even wider. Dean would never judge someone else for who they wanted to be with, or loved. Even if it wasn't the case here. "Dean has never mated before." That wasn't a hint or anything, just a fact. But as soon as his statement was there, it was gone as the quickly as the subject changed.
"Come, Dean will show you!" He would lead Ritchie to the refreshment table, specifically the alcohol one. Where Dean would grab a bottle of vodka. "This is spicy water!" He spoke proudly showing off the bottle just before he did what he had done with Danny before: opening the bottle and guzzling down its contents in a matter of seconds. With a refreshed sigh, Dean set the bottle down and he looked at Ritchie, the action having little to no effect on him.
