with one or two fingers on the inside of your partner's cheek (like a fish-hook), and immediately following oral sex or intercourse, pull out your dick and blast your seed into the nostrils and eyeballs of your partner. he or she will duck and dive to protect their face from your dick juice. just like a pissed off marlin on a big fucking hook.

Taking a crap on the back of a chick and then forming it into a Marlin's Fin. After you are finished sculpting you stick her from behind.

When performing anal sex doggy style, and the female becomes a bit jumpy, the male reaches and fish hooks his partners cheek with his index finger.

When a woman's anus is too constricted for penile penetration and the male must finger her anus in order to relax the sphincter in preparation for anal sex.

it is large

Putting two fingers in a girl's mouth and two fingers in her vagina. Then raising her above your head and shaking her violently to resemble a Marlin flopping in the air
