Getting completely and totally shitfaced out of your mindpiece. Being wastchiff takes being "wasted" to a whole new level. When you get wastchiff you end up treating people like shit, drunk dialing your grandma, and beating your meat to gay porn. You aren't just getting drunk, your getting brownout at the very least. You can also achieve the "ultimate wastchiff" by smoking an incredibly large amount of ecstacy laced weed. Usually this ultimate state of fucked-up-ness is graded on a scale 1 to wastchiff
