Single Life Under Cover
Living the Single Life Under Cover. Being pseudo single while the girlfriend is away for a couple of days. Walking around naked, picking your nose, scratching your arse, farting, eating chilli and hotdogs, not brushing your teeth, deoderant shower, and all the other things one did while real-single - 'cause no one is gonna tell you not to.

- This weekend I'm a slucker
- Damn, what a lucky cunt, he's slucking again
