My friend told me he’d been working out during the summer, however, I knew he suffered from FOSS. So, I felt bad for him honestly

Acronym for Full of Shit Southerner. Used to describe a person from the South (including but not limited to the following states: NC, SC, GA, TN, AL, MS, LA, VA and KY) who is politely being evasive, untruthful, disingenuous and/or passive aggressive. A common behavior found in regional southern culture and widely deemed unacceptable to a northerner, who typically values being forthright. For example, the acronym is applicable when someone is 'yessing' you to death and truly means 'no'.
"That person was a FOSS. She kept saying she's love to buy a timeshare from me, and when I asked her for her credit card, she made all sorts of excuses."
"Total FOSS's. They're from North Carolina."
"Total FOSS's. They're from North Carolina."
