AtD translation: or gone out and raised hallelujah with

[Mike Jing]

P53.1-9   “Yes here,” continued the Professor, nodding down at the Yards as
they began to flow by beneath, “here’s where the Trail comes to its end at
last, along with the American Cowboy who used to live on it and by it. No
matter how virtuous he’s kept his name, how many evildoers he’s managed to
get by undamaged, how he’s done by his horses, what girls he has chastely
kissed, serenaded by guitar, or gone out and raised hallelujah with, it’s
all back there in the traildust now and none of it matters, for down there
you’ll find the wet convergence and finale of his drought-struck tale and
thankless calling, Buffalo Bill’s Wild West Show stood on its head . . .

What does "raise hallelujah" mean here?
