I think I use "massive" and "huge" as adjectives with both male and female bodyparts. The point being that the bodypart is pejorative, so a "massive" attached just means they're even worse.
In this case, I called Barba Red Astaire whatever a "mad twat" and that seemed quite perfect, especially given that straight afterwards he decided to write two different responses to the same post, almost as if that, as well as me joking about him having a mental breakdown, he actually is having a mental breakdown.
He seems to have an amusing nervo at least every couple of weeks and staggers around like a ranting tramp shouting at the traffic.
