A person who will initiate and wishes to, or attempts, to become involved, usually romantically, with a man or woman, who is
already in an established relationship, (e.
g., married, engaged, boyfriend/girlfriend, etc.), but will not put forth the
effort to obtain and establish a relationship of their own. To engage in an affair or come between
two parties. Such relationships might be deemed genuine, at least from the perspective of the "side slipper," or merely an attempt by such a person to interfere with the sole purpose of causing temporary or permanent disruption of the established
party's relationship. (May also be seen or written as "Side Slipper").
Variation: To "side-slip."
Josie just can'
t seem to get away from the life of being a side-slipper. She keeps trying to get with
Curtis but knows he and Laura are engaged to be married. She claims she is actually in love with him, but I think she merely wants to cause trouble to break them up. If she spent more time trying to find someone of her own, she wouldn't have time to worry about what others are doing.
Larry thinks he can
slide-slip between Diane and Ronnie. He's been after her for a while, but might experience a rude awakening.
