A sequence often used at the start of rock songs. It has several variants including "A 1 A 2, A 1-2-3-4!"

However it sounds a litle stupid in the middle of songs (see Altogether Now by the Beatles).

ALso the first 4 numbers!
1-2-3-4 cue brilliant rock or really lame derivative song.

When you wanna move that special homie of yours that makes you feel some typa way up to the next level.
To put it simply, the levels of homie represent the levels of a relationship.
Homie level 2: dating
Homie level 3: engaged
Homie level 4: married
it is simple.
"hey, wanna be my homie level 2, 3, or 4? ;)"

A meme within the Taylor Swift fandom created after a video went viral of a girl screaming “1 2 3 let’s go bitch” during the song Delicate at Taylor’s reputation Stadium Tour in Pasadena. This trend caught on quickly, to the point where Taylor even started to join in by counting on her fingers. To this day, the meme lives on.
Taylor: “We can’t make, any promises now can we babe, but you can make me a drink...”
