"It actually made me a bit angry.
"I'll just text her a smiley face!"
Kyrgios's exploits topped what had already been a dramatic eighth day of the championships including defeat for Maria Sharapova and the sight of distressed world No.1 Serena Williams serving a game of double faults in a third-round doubles match with sister Venus, before retiring with an illness.
Roger Federer's vintage Wimbledon continued, though, as he glided past Spain's Tommy Robredo 6-1 6-4 6-4 to reach the quarter-finals of the grasscourt slam for a 12th time.
The 32-year-old, yet to drop a set in four rounds, dazzled the Court One crowd with his artistry, making the game look ludicrously easy against the 22nd best player in the world.
"I feel physically in tip top shape," Federer, who now faces an all-Swiss quarter-final against Davis Cup team mate Stanislas Wawrinka, told reporters, although his mood may have been soured later as Switzerland lost to Argentina at the World Cup.
While Federer is facing an unusually busy schedule at Wimbledon because of weather interruptions, Wawrinka will be playing a third match in three days on Wednesday.
Australian Open champion Wawrinka beat Feliciano Lopez 7-6(5) 7-6(7) 6-3 without any major alarms although the match ended with the players in a heated argument at the net.
Big-serving Milos Raonic celebrated Canada Day by becoming the first man from his country to reach the quarter-finals at Wimbledon in the professional era, beating Japan's 10th seed Kei Nishikori 4-6 6-1 7-6(4) 6-3.
Wimbledon's second Tuesday is usually reserved for the women's quarter-finals, but with the schedulers playing catch-up after this year's rain delays, only two took place.
Czechs dominated the bottom half of the women's draw where Lucie Safarova's 6-3 6-1 defeat of Ekaterina Makarova set up a semi-final clash with compatriot and 2011 champion Petra Kvitova who defeated unseeded Barbora Zahlavova Strycova 6-1 7-5.
With a Czech finalist guaranteed, the top half of the draw took a further twist when Russian firebrand Sharapova, despite saving six match points, had her hopes of celebrating the 10th anniversary of her sole Wimbledon triumph with a sequel, rudely ended by dogged German Angelique Kerber.
The screaming fifth seed threw everything in her formidable arsenal Kerber's way, but after recovering from a wasteful opening set tiebreak to level, she went down 7-6(4) 4-6 6-4.
Though not the victory the French Open champion craved, she showed true champions' spirit to haul back a 5-2 deficit in a thrilling finale
