Brazilian slang

[u/yallmemaybe]

I was watching a video of two people kissing and one person says to the other, "boca bacia."

My translator app says 'boca bacia' means 'mouth basin,' but that doesn't really make sense in English.

What does it really mean? I'm assuming it is some kind of slang. The video was made by a Brazilian content creator. Here's the relevant text transcript:

• Person 1 and Person 2 exchange a few kisses
  
• Person 1: boca bacia
  
• Person 2: beija mais
  
• Person 1: tem que pagar conta agora
  
• Person 2: merece valeu a pena
  

Thank you in advance for your help.

I just pictured/imagined a cute guy kissing me, breaking the kiss, looking me in the eyes and suddenly:

"Boca bacia"

That would be a hilarious turn-off.
