Gonzaga star Drew Timme's gotta put some money in the swear jar after the Bulldogs defeated TCU to advance to the Sweet 16 on Sunday ... 'cause he dropped an F-bomb on live television right after the big win!!
Drew was pretty stoked after sealing the 84-81 victory ... and he got caught up in the moment during his postgame interview as he explained the pressure he and his teammates felt to win the game.
"Before they announced our starting lineup, it was like, 'in seven straight Sweet 16s,'" Timme said in the interview.
