British number one Heather Watson has apologised after becoming the latest player at Wimbledon to be caught using foul language.
The 23-year-old had a point docked after being slapped with a code violation for an audible obscenity.
It comes after several players - including number one seed Serena Williams - turned the air blue on Monday.
Asked about the incident after going through to the second round against France's Caroline Garcia, Watson put it down to "the heat of the moment".
She said: "I don't even know what I'm doing until after it's done, I don't even realise I'm doing it.
"I say things that I shouldn't say. I apologise to anybody that is offended. I need to control it and I just can't."
Watson had already got in trouble on Monday for racquet abuse before the third set of her match was postponed due to lack of light.
She was asked whether fans could expect more aggression from her after she slapped her thigh following the code violations.
"Hopefully controlled aggression - it doesn't feel so good after the match," she said.
Five-time Wimbledon champion Williams was also cautioned for an audible obscenity on Monday and put it down to being "really nervous".
Meanwhile, Britain's Liam Broady also faces a hefty fine after he was caught swearing on court.
And Australian Nick Kyrgios was forced to deny claims that he had called an umpire "dirty scum", insisting that the insult had been directed at himself.
Players can be fined by up to 20,000 US dollars (over £12,700) for a code violation.
If a violation happens during the warm-up or a match it initially results in a warning.
A second offence can lead to a one-point deduction, a third in losing a game and a fourth can see a player potentially lose the match.
