One of the child beauty contestants, about age 9, does a routine with music and moves that are mildly suggestive.
Grandpa refers to Frank as a "homo" and later uses the term "fag rag" for a gay porno magazine.
When they stop at a gas station convenience store, Grandpa tells Frank to get him some porn (adding that he wants the heavy duty stuff) and for Frank to get himself a "fag rag." We then see Frank looking over the magazine covers (with titles such as "Buns" and "Big Butts." Some of the women show cleavage and a few are seen in skimpy attire (such as bra and/or bikini tops), but there's no outright nudity.
In the background of a shot, we can see the image of a woman in a small bikini swimming laps in a pool (she's underwater and we can tell she's in a bikini, but can't see any details).
A man talks about f*cking a lot women. He then tells someone who is 15, that he should be f*ing those young jailbait girls.
There is a reference to second degree burns on a man's "Johnson" from sexual activity.
Characters look at porno magazines. The camera gives us a close up and we see on the top left a man and a woman having intercourse, on the top right a woman in black leather showing cleavage, on the bottom left another woman in black leather showing her entire butt, on the bottom right two women holding each other, and in the middle (the most noticeable) a woman wearing white underwear pulling her butt cheeks apart. This is very brief.
Some other moderate sexual references are made, mostly through conversation.
