I certainly hope that these were intended as a gag gift. Most guys go out of their way not to walk around with that kind of silhouette, outside of a bedroom.
The only person that I can remotely imagine that a guy might want to impress that way is a potential sex partner. And in most cases, if she notices at all, I doubt she’ll be overly impressed by a fellow who appears to be in need of immediate medical attention because he’s taken an entire bottle of little blue pills.
On the other hand, this is pretty much the only “male enhancement” I’ve ever heard of that would definitely work. 😉
