this is a term describing a person who picks and chooses his jobs usually taking the gravy work for himself and leaving the shity work for all the others picking through the pile or whatever
he was picking through the pile of work orders so he could find the car he would flat rate the most time in the least time and when they caught him they said hey dont pick through the pile you fucking sifter
A misinterpretation of the lyrics from my generation, by Limp Bizkit. Can be used in many ways. The choice is yours.
*my generation plays in background* Andy: Did he just say Sifting through the Matthew's Fridge
Kyle: no what's the fuck is wrong with you the actual lyrics are take 'em to the Matthews Bridge, what would that even mean?
