When you hear guys say "I have a semi..." does the word mean "it's so/so hard" (as in semi-hard) or does it refer to the vehicle that drives down the road? As in, "instead of floating a torpedo, he drove a semi?" And do you pronounce it semi (rhymes with hemi) or semI (like the truck?) Just curious. When i first heard people using the phrase growing up, since people around me pronounced it with the long I, I thought of the truck on the highway!
