Gaga Straight
When a guy who's usually into guys becomes straight because he's so in love with Lady Gaga he thinks she's the only woman worth having. It's like he's been completely replaced by a diva.
'I don't like women anymore. I only like Lady Gaga.'
'He used to be my crush. Now he's singing 'Poker Face' at me like I'm his new love interest.'
'He dumped his boyfriend for Lady Gaga. Now he's a walking fan club for her.'
