bushman's toothpaste
Semen, cum, male ejaculate, etc. Derived from the days when toothpaste was not as freely available and a 'bushman' (Australian outback adventurer) had to rely on his own supply.
Example 1: I've been stuck in the bush for the last 3 weeks and had to rely on the ol' bushman's toothpaste to get by.
Example 2: She was gobblin my knob and I gave her a squirt of the ol' bushman's toothpaste.
