American lobster - Wikipedia, the free encyclopedia
: "Lobsters do not mate for life, contrary to some myths. The female seeks the most alpha male she can find, and the male will mate with as many females as he can."
So if you want to scare a man off, do not refer to him as your lobster. Better options would be your whale, gibbon, swan, gerbil, Canadian goose, or penguin. Actually, there are a lot of birds (condors, cranes, barn owls) that do, if you want to go that route.
