This is a common word among Marines and Sailors who frequent the bars and clubs ALL OVER JAPAN. A Japahoe is not only "Around American military bases" but can come from any part of Japan. More commonly, Japahoes are found in Hiphop and Rap clubs looking for Black American military guys. These American men are taking advantage of these women who do not understand American Culture of hit it and quit it.
Its not called "Buy-me-drink-me" its called "Buy-me-Drinkie" and you will NOT find a Japahoe here. These are snack bars where Japanese men come to have a female drinking companion. If you think you will get ass at a place like this you are SADLY mistaken, and you will probobly loose your genitalia to the local Yakuza for trying to tap that.
The women at "Snack" bars are very good at getting men to spend money, so any time you hear of an American guy hooking up with a Buy-me-drinkie girl, its a flat out lie.
When you fail at something in life (eg. failing an exam or not getting a job), go home and spend an hour just standing in the shower, propping yourself up against the wall with your eyes on your feet.
