Double Subverted: However, it turns out that Bob is still secretly very insecure, and carries a BFS because it's even bigger.
Parodied: Bob attaches two pink balls to the hilt of his BFS.
Zig Zagged: B.O.B. is a combat robot with a very male voice who uses a wide variety of guns and vaguely phallic shaped blades. Some accuse him of compensating for his lack of genitalia by using overly large weapons and tough guy talk, others figure he just uses them for effectiveness and doesn't care about organic thoughts. It turns out his designers made him like that in an attempt to make him too intimidating for anyone to want to fight... except for one who really was just compensating for something.
Averted: Bob carries a normal-sized sword. Penis size is never brought up.
Enforced: "We don't want the viewers to make any mistake as to how manly Bob is. Let's make him carry a huge sword or something to reinforce the image".
Lampshaded: "That's a pretty... phallic sword you've got there. I guess the little sword must not be slashin', eh? EH?''.
Invoked: Bob is insecure about his small penis, and decides to prove to the world he's a Badass by carrying a big sword.
Exploited: "Hey you! You with the HUGE sword! Aren't youCompensating for Something? (Cue the warrior getting in a mad rage and making a mistake or deciding to strike at the taunter rather than another, more fragile target.)
Bob decides that it's not the size that matters, it's what you do with it.
Bob is insecure about his size. But he knows that if he overcompensates to make himself feel better then everyone will know. So he doesn't even bother doing anything crazy manly.
