England claims to be a gentleman, but he becomes this when he's pissed off.Romano, especially when he's around Germany.Several characters from Axis Powers Hetalia:.

Agito from Air Gear has the F word as his catchphrase.

Special mention goes to Sanji, who was actually raised by sailors and who trumps them all without even trying (his catchphrase is shit, usually as a prefix for someone male's nickname).

The entire male half of the Straw Hat Pirates from One Piece though justified in that since they are pirates, they would naturally 'swear like sailors' all the time.

Revy of Black Lagoon is by far the most foul-mouthed character in the series, and is the most frequent contributor to its high volume of F-Bombs.

Bando from Elfen Lied has the filthiest speech pattern in the entire series, due to him being a rough and tough guy with anger issues and being a Jerkass.

He also enjoys bringing up embarrassing bodily functions rather often.

Edward Elric from Fullmetal Alchemist sometimes has the tendency to do this, mostly when angered by mentions of his height.

In the English dub specifically, the swearing overall isn't that much less than The Wolf of Wall Street! This makes the one time they do swear up a storm in the final episode have that much more impact. In contrast, the two Demon sisters, Scanty and Kneesock, are two posh, high-class villains who never swear, despite their roles as the antagonists (though they do sometimes indulge in occasional sister-on-sister fun times). Ironically, Panty and Stocking Anarchy, the two most foul-mouthed characters on the show, are angels.

The title protagonists from Panty & Stocking with Garterbelt swear so often and with such vulgarity (especially in the English dub, holy fuck) that they could practically be called the Trope Codifiers.

Casting slurs while in a position of power might be a sign of corruption of the person (or the entire institution!). Someone who swears to a select group of people may be a racist/bigot.

Another who uses slurs as a weapon to break people emotionally can say much about how insensitive or callous they are at their core and also hint exactly to the sort of failing they have.

It can also coincide with traits like Beware the Nice Ones or Stepford Smiler.

If a character rarely swears but in profuse/intense vulgarity on those rare moments, then it might be a sign that the topic is either a Berserk Button or Serious Business issue for the character and/or that their stress level has reached a breaking point.

If a character swears around their friends, it can (but not certainly) hint to a degree of trust that swearer has toward the other, not holding back their thoughts but being honest about their feelings.

Someone who swears frequently as if it was punctuation may come across as irreverent and casual.

The various circumstances of how or why a character swears also may say a lot about the other facets of their personality.
