How its written: Pff... Bah ca m'fait total'ment flipper, la. What I heard as a native English speaker: Ba ca mmmhmfaitmm something something flipper la. I'm well on my way to mastering French! :)
vowels are so easily " lost" because they are " like breath"- breathed out ( except in Finnish: they can be breathed in& OUT 😊) also, French language changes rules in order to SOUND beautiful & fluent ( mon fils observed this after been living in France for 2 yrs...)
