When your girlfriend moves across the country to be with you, but has to go "home" for a cardiology appointment, you have ample opportunity to "Swink" it. Also known as: ignoring her and letting her find you on several dating websites saying you're wealthy, single, and looking for a relationship. Luckily for you, she will be 1800 miles away and therefore incapable of doing anything about it. You will have zero consequences and can easily pretend she doesn't exist. Also known as: you are a spineless cheating bastard.
If the description above portrays you, you must be Swinkin' it..
