a fancy way of saying the classic your mom joke.
guy: ah yes sir, thou art quite annoying.
other guy: FIE! thou mother/thy mother is incredibly ravishing.
something an absolute fucking loser says when good things happen.
guy 1: omg i got into harvard im so happy
absolute loser: dababy les go
Used when something good happens, replacing "yay"
only used by dumbass middle school kids
"Ayyyy no quiz? dababy les go!"
