I was watching a recent replay of a CS:GO match. For some reason the casters kept talking about a team "keeping great control of banana". For example at around 19:04 in this ESL video. At first I thought I misheard, but then I checked various maps online, including this one:
And for sure, there it is: "BANANA".
All of the other callouts / names on this map make sense somehow. Is there some inside CS:GO joke that I'm missing here?
Why is it called "Banana"?
