Sound barrier 

When, in a relationship, farting in front of each other is not acceptable. Breaking the sound barrier is the point at which the first fart takes place in front of the significant other.

I always have a tummy ache when I leave my boyfriends place.

Why?
Because we haven’t broken the sound barrier yet and I have wicked gas.

sound check 

Asking for a Sound check is a different way to ask you co-pilot if you have any visually noticeable drug residue in, on, or around your nostrils. Usually after insufflating an illicit substance in powdered form.

Yo, Jeeves can I get a sound check?
