Hmmmer is just hammer with an extra m and no a. It came from one of Markiplier's videos of Henry stickman completing the mission. He said "hammer,hammer or hammer" he tried the first hammer option he died then he called the second and third option "hmmmer" and "Hmmmmmmmer"
You can use it in a sentence when you use the word "hammer" for example hammertime! ----> hmmmertime! To seem a bit funnier.

Technically just hammer but replace the a with m. in one of Markiplier's videos of Henry stickman completing the mission.
Markiplier said "hammer,hammer or hammer." And then he used one of them then failed and said "hmmmer" and once more after that.
