 Get the Boomer Barriermug.
Get the Boomer Barriermug. Noun. The line between the layer of melted marshmellow and the rest of the hot chocolate - clearly visible in a clear mug by a marked change in color, but otherwise determined by a sudden and marked change in temperature
Be sure to sip that hot chocolate slowly - if you cross the marshmellow barrier you'll scald all the way back to your tonsils.

Get the marshmellow barriermug. 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.
