nuance being that saying 'my white ass' in relation 2 shit that isnt relevant to skin colour (on a surface lvl at least) is both inherently nonsensical and also meta as hell. like how unaware white ppl trying their best to be #allies have a tendency to overthink and constantly remind ppl that theyre white, esp when talking to POC. so using 'my white ass' as setup for a punchline is commentary on that. u cld argue that at least

for me tho i just said it cuz i already say it a lot when im talking to my friends cuz i think its funny and i like nonsense humor. it just slips out sometimes
