I've usually only heard those terms used in describing the actions and sounds of flat tires.....You know, when the air goes away, daygo wop, wop, wop.....(TIC, NOI, *BG*, etc.) Which brings to mind a story.....I can hear the groans already....Son says to Dad, Poppa, can I have a Ginuea Pig?.....Poppa replies, Aw Son, why not find yourself a nice Irish girl? AGAIN REMEMBER TIC, NOI, *BG*
