Underarm 

The soft pocket of skin beneath the shoulder that joins the inner part of the arm to the body.

The pretty girl's underarms were soft and smooth, hairless and extremely ticklish to the touch.

Underarm 

The wrong way to bowl in a Cricket match. This happened most memorably in a Australia vs New Zealand match in 1981 where the dirty Australians were very unsporting and stole the series by bowling the ball underarm instead of overarm, preventing the New Zealand batsman to score the 6 runs needed to win the series. Goes directly against the Gentlemanly nature of the game.

"No, Greg, no, you can't do that" (Ian Chappell, Commentator of the game and the brother of both the Aussie Captain, Greg, and the offending bowler, Trevor.)

The Underarm '81 incident is "the most disgusting incident I can recall in the history of cricket" (Rob Muldoon, the then Prime Minister of NZ)
