I've heard this term used by young Korean men who put their index fingers together and ram their other male friends in the arse when they bend over and yell "BASHA!!!". It is done in fun and is not homosexual in nature. It's like a titty twister.

Actually Basha - meaning a shelter - comes from the Bengali for 'house' and dates back to the first British military presence in India in the 18th century. (British Army Standard Hotel Accommodation is just a 'backronym' i.e. a made up origin that makes sense.)
