Explaining English sayings

These were sent to me by an English friend.

“They used to use urine to tan animal skins, so families used to all pee in a pot. Once a day it was taken and sold to the tannery. If you had to do this to survive, you were ‘piss poor.’ But worse than that were the really poor folks who couldn’t even afford to buy a pot. They ‘didn’t have a pot to piss in’ and were considered the lowest of the low.”

“Most people got married in June because they took their yearly bath in May, and they still smelled pretty good by June. However, since they were starting to smell, brides carried a bouquet of flowers to hide the body odor. Hence the custom today of carrying a bouquet when getting married.”

True or false?
