A person with
the lobster disease is someone
who has the recurring problem of catching feelings for someone
after having sex, despite initial intentions
of keeping things casual. Once they've shared a sexual experience with
one another, emotions
unavoidably develop and a desire to mate arises, an incurable side-effect resulting from the lobster disease.
The term lobster disease has an indirect reference to a bit from the television series, Friends, where Ross
is upset because
Rachel and him weren't getting together whereby Phoebe
reassures him saying that Rachel is his lobster. Lobsters are known to mate with only
one partner for their entire lifetime.
