Stands for "Simply Don't Give A Fuck". Relative of idc and idgaf. More common on pins and bumper stickers than in conversation.
Hearing a crash, the man ran outside. He found his mailbox had been destroyed and his dog had been run over. The car responsible barely gave him enough time to read its rear bumper sticker: SDGAF.
