When you go on a trip abroad and make a forever friend with a bro, typically bonding over a love of inappropriate grinding, asian food and skimpy socks. Other people might laugh at your bromance, but you know it's a beautiful thing and definitely doesn't make you gay...
George: So are Alex and Steve dating now then? I didn't realise they were gay.
Adam: Nah, it was just a Holiday Bromance I think, Alex is having some trouble moving on though...
