Sandtrap 

When you have sex on a beach and you get sand on your penis and don't wash it off before penetrating the vaginal cavity.

John got caught in a sandtrap last night and shot himself after.

flaming sandtrap 

When engaging in rough sexual intercourse on a sandy beach, the male sticks it up her anal cavity and continues with anal until he goes inside her rectum. He continues to pull out quickly leaving the loose anus open and throws in a handful of sand off the beach. This combines with the already present semen to form an unstoppable cement-like combination which when dry, the female will later refer to as a fire in her asshole.

Alyssa: JAKE my asshole is on FIRE

Jake: GENIOUS GENIOUS GENIOUS

Mouth Sand-Trap 

When one chokes from having cotton mouth after eating dry ass Austin Toasty Crackers with Penut Butter. (Usually when no water is present)

Those crackers Joe gave me were a mouth sand-trap and I almost died because I had no water and a severe cotton mouth.
