The TLC reboot has the same level of language as the original series.
The show is well known for it's very strong, non-stop profanity, especially during the first seven seasons (when Frankie Boyle was one of the panellists). Words like "Fuck", "Shit", "Asshole", "Twat", "Wanker", "Bollocks", "Arse", "Cunt", "Bitch", "Tits", "Whore", among any other swear word imaginable has been used on this show. Homosexual and racial slurs have also been used.
As noted above, Frankie Boyle was known for using a lot of language and terms for shock value when he was on the show. One episode had him using the racial slur "Nigger" in a racist way.
