Here's why:
* "Tu" is a common word in Spanish and Italian, meaning "you."
* "Ke" is similar to "que" in Spanish and Italian, meaning "that" or "which."
* "Pedo" is a vulgar word in Spanish and Italian, meaning "fart."
Therefore, the phrase "tu ke pedo" literally translates to "you that fart" or "you which fart" in Spanish or Italian. This is a nonsensical and rude phrase, and it's likely not used in any real conversation.
If you heard this phrase, it's possible it was used:
* As a joke: Someone might be playfully using it to be humorous or offensive.
* In a made-up language: It could be part of a fictional language or slang.
* In a song: Music sometimes uses made-up words or phrases for artistic effect.
Without further context, it's impossible to know the exact meaning or intent behind "tu ke pedo."
