A slam sack is a body used for fucking. This usually refers to females, but has come to encompass anyone who fits the description.

When a perfectly delightful knee is bent over a perfectly wonderful leg; with a hot wet sack of dez nuts or a elegantly shaped pair of humanities future calmly resting on relaxed knee - waiting to meet the better half.
The package was lowered onto my knee creating a hot wet sack wrapping my aching knee in warmth and kindness.
