It's a half-joke. Chuds look down on lanceros because they don't do enough to prop up their sense of masculinity. I've heard them called "feminine", "for women", because they are thin and look delicate, like cigarettes in cigarette holders women used to smoke in the 20's.

Thing is though, they tell on themselves. Lanceros are the most complicated and rigorous form of cigar a master can roll, and the taste can be very unique because there is minimal filler tobacco so you can theoretically focus on the wrapper (outermost leaf) while also making them the most difficult to smoke. All of these are reasons they are often considered the best form by people who are actually really into cigars. So, they just give away they don't know what the fuck they're talking about. When people bring up lanceros being for "ladies" I just usually say something about women having better taste.

Of course, some chuds will smoke lanceros. It's not a hard rule, but they usually go for the thick gauge cigars that makes them feel like big boys.
