Neil : "Ah, here's one. This means that someone has just done something which has never been done before. 'Richard Moore of Sugarland, Texas, hollowed out an eggplant and filled it with hot sauce and nickels.' And amazingly, it's not a weird sex thing. 99% of all new human behaviors are weird sex things. But not in this-- oh, no, it is a weird sex thing, yeah."
It's clearly sexual from the context of the meme. Pretty much any time this happens, it's sexual in nature. Otherwise it would just be confusing rather than presented as humorous.
If that were entirely true, a "power bottom" would make no sense.
The terms sexual usage originated in gay circles where it only delineates who penetrates and who gets penetrated. Traditional views on sex ascribe a submissive or passive role to the bottom and an active or dominating role to the top, but you can totally have a power bottom who takes control and an active role in the intercourse but is the one getting penetrated.
