Dirty Fergie 

Is when you crap in a toilet that has yet to be installed or is just being stored.

After my brother poured a coke on my head at my nephews 1st bithday party,I went into his garage and left a dirty fergie in his future throne.

DIrty Fergie "Office Style" 

Is when someone else left the shop bathroom in such a stench and mess, you go into the closed down office ladies room and drop a deuce in a toilet that's been turned off because of a broken pipe.

Worker 1: You went in the girls room up front? That's been closed for six months because of that broken pipe!

Worker 2: Well now their not using it for at least a year after I dropped that dirty fergie "office style" on them!

Dirty Ferdie 

The Dirty Ferdie is when a losing field hockey team has their tallest defender sprint to the 50 yard line and take a massive shit right there in the middle of the field. This will distract the opposing team enough that the losing team should have the opportunity to score to hopefully tie the game. This is considered a "fool proof plan" in the game of field hockey.

The team was losing, but tied up the game when they pulled the dirty ferdie in order to distract the other team.
