Nah, "baisez mon pote" means "fuck my friend". A proper translation would be "pote de baise", although to be honest I've never heard it in use here — the more common expression is "plan cul", which minimizes the "buddy" part but can obviously cover a lot of nuances.
At least that's what I'm guessing from the TV shows, everyone I know is either in an actual relationship or does not have s*x at all 🤷
