Get the Guake mug.
The act of giving your partner sloppy head (sucking duck). This is the sound one so mouth will make when giving head with a generous amount of saliva and slurping.
The word “guak” is derived from guacamole , the word used to signify that you want head without others knowing.

Girlfriend: do you want guacamole on the way home today?
Boyfriend: yea we can get some before we go to the store.
