The Etsy shop Sweet Perversion has created a unique way to express your sentiments that normally would not be considered socially acceptable.
The Sweet Perversion stationary is a basic blank card printed in soft white paper and comes in a cool envelope. With greetings such as "I love you like a back-alley hooker loves crack," "Happy Birthday, I hope you catch herpes" and "What would Jesus do? He'd probably slap you in the face," it is too hard not to hope that one day you'll be handed one of these laugh-out-loud, bittersweet cards from your friends and family.
The Sweet Perversion cards are a great way to be a little more passive aggressive to those friends and family members you are not too fond of.
