Breadknife 

Taken as a spin off from the term "to cut someone's lunch" which in turn means for one person to 'hit on' or 'flirt' with another person's partner/girlfriend/spouse.

A breadknife is used to cut a sandwich, which may be someone's lunch.

A friend decides to flirt with your grilfriend when you are not present, he could be described as cutting your lunch, and thus you are entitled to call him a "Breadknife"
