Shake and Carl are sexual deviants, and as such, reference the vagina and penis fairly often. Meatwad mentions "taping down his junk". No nudity.
You fight pubic crabs, literal crabs that are formed from Carl.

In later levels, shake gets to use a shotun, but the shots are very, very cartoonish
The weapon with the most graphic effect is probably the chainsaw, as when used to attack enemies, they spurt some blood
Minimal. There is little to no blood and no gore at all.

Even though the game has an M rating, expletives such as "f**k" or "s**t" are censored, however, swear words such as "bitch", "ass" and lower have free reign.

There is a trail of beer cans around Carl during his boss fight. The Mooninites mention drinking and doing drugs, but are never shown to actually do so.

None, everything is played for laughs.
However, some may find the levels in the depths of Hell to be slightly overwhelming.
