I keep seeing people post "I'm yelling timber" in attempt to quote the lyrics from the song Timber. But she doesn't say "yelling" she says "I'm going timber". Notice Ke$ha pronounces a "G" after "I'm" followed by "owin" - saying "going". Maybe since my accent heavily differentiates from her's I may be mistaking what she truly says, but I think not.
I thought Timber meant boner though, which is why I was confued with whatever she said.
Timber is just another metaphor/punchline for "It's goin' down." Similar to, "It's goin' down.
Basement." on "My Chick Bad." Though, I'm sure if different artists used "Timber" in
a record, it could very well be used for "wood" or "boner." Many uses.
