What does going all the way entail?

Does it mean, orgasming or actually the whole act of sex.
I ask this question because my friend Amy, believes that going all the way only means ejaculation.

I am in a situation where she adamantly believes she is correct and I adamantly believe she is incorrect. Wee arrived at this situation when wee were questioning one of my bi-curious friends actions,

I firmly stated

"No he didn't go all the way no, he didn't have sex with that guy, he only did oral and the guy ejaculated. That doesn't mean going all the way."

then she replied

"You're wrong Eisen, he did go all the way because going all the way has two contexts"

I then curtly replied

"No, you're wrong, going all the way only means one thing and that means a home run, makin' whoopee,  grand slam, to dine in the Y, etc etc."

On another note, she likes to dye her hair blonde from time to time.
Methinks her blonde hair is getting to her. LOL! (pun intended)

So again back to the question. What does it mean?
