It means that they are expressing how they more than hate someone as to the very being of them guts and all,
When you hear a person say: "I hate their guts", --are you always mystified and puzzled just as to why they would choose to take strong objection to someone's intestines, entrails or bowels?
It supposedly originates in Ancient Egypt where the Pharaoh would execute his enemies or dissidents and have their entrails ripped out while dying.These would then be preserved and put on display as a warning to show what happens to rebels or protestors.The records of these deaths and accompanying pictures were written in hieroglyphics for all to see regarding whose guts the Pharaoh hated.
"I hate his guts, and Flanders is his name". To hate someone's audacity?
Lol...I use this phrase when I truly dislike some passionately.
" I hate him/her with the fire of a thousand suns"
" I hate him/her with the fire of a thousand suns"
I am puzzled even when somebody uses the word "hate" cus to me hate means.."they stole my crayons I hate em"..8)
