[@Altered Tundra] One of Tate's theme songs relates to that saying:

Tate isn't as disastrous as Alex but that's basically what that saying means. Someone who keeps getting worse and digging their grave. Due to Tate's foolhardy nature, I thought it was fitting since he does what he wants with little to no thought xD. 

The saying just means you can start disasters and shit (and not rlly caring for the consequences) xD 

AT LEAST THAT'S MY INTERPRETATION
