The gift needs to be able to come off as a genuine gift so there’s some plausible deniability…
Edit: Just so it’s clear, this is purely hypothetical. I just thought of the idea and thought it would be funny to see what a random person on Lemmy might think. This isn’t a serious request and none of the suggestions will ever actually be used.
The name Trojan refers to the fact that it’s intended for horses, with anything under 37cm being x-small.
Discreetly open it and replace the contents with x-large.
If they open it, it’ll make them feel even littler.
