To (prospectively) have penetrative sex with a female.

Possibly of Australian origin, this jocular euphemism for sexual intercourse is typically used by men discussing the attractiveness of a specific (but non-present) woman.

The phrase may be a derivation of the derogatory joke "She's so loose, it was like chucking a chipolata up the high street" in which the male speaker not only slanders the large size of the female subject's vagina, but also disparages the size of his own penis.
"That Helen Mirren's hot for a mature lady."
"Damn right mate, I'd chuck one up her!"
