Gambling to the point of losing one's mind and thus losing their entire life savings.

Derived from the phrase: Sloppy drunk
Matt: Alex stop betting man you keep losing!

Alex: Shut the fuck up man ONE MORE HAND!

Matt: I ain't being a part of this and your sloppy gambling. Lose it all for all I care, bitch.
