Just days after TMZ Sports posted footage of Conor saying he "owes" Nate a 3rd fight out of respect -- Nate seems to be poopooing the idea ... and is now setting his sights on The Eagle.
"Kabibs hiding scared cause I slapped the sh*t out of him," Nate posted ... "Conor already got his ass beat twice."
"Where the f*ck you at kabib?"
Nate and Conor fought TWICE back in 2016. Nate won the first fight, choking McGregor out in the 2nd round.
When they ran it back a few months later, Conor won a majority decision after 5 bloody rounds.
