barrrrrrn!
The sound that things of massive size make as they swing through the air. This could be used in narrative (... and she had massive collosal knockers going BARRRRRRN!), or as a sound effect in a commentary as the girl who is sick of you talking about her premature tits turns around to thump you. This can be more effective if you sing songs from War of the Worlds to the girl first.

My mate Greg Jolley was the undisputed master of barrrrrrn! Whatever he mimed, whatever he was describing, this all-purpose sound effect would be in there somewhere. Examples...
(Describing an episode of Hammer House of Horror) "And the hitch-hiker raises his hand up to the bloke's face like this, barrrrrrn..."
"And this massive aeroplane went barrrrrrn..."
"And then this bloke came out and I went 'peg it!' and we went barrrrrrn..."
