Mac Guy (Nickname) Refers to Justin Long, star of the Mac commercials.

Devastating news to report this morning: The Mac Guy, 30, and Drew Barrymore 33, have officially called it quits after nearly a year of dating, a break-up confirmed by Barrymore's publicist. Apparently, he was into fun stuff like movies, music, and podcasts, while she was into infrequent showers, random displays of crazy, and fucking random men. Unfortunately, the Mac Guy's operating system simply wasn't compatible with batshit fucking insane.
