The Word -Slimsy

The man moved quickly to the river that crisscrossed throughout the city. He handled the boy carelessly, giving every corner of a wall, doorframe, and reaching branch the opportunity to exact the revenge of the people. If the boy didn't have a headache from the wine before he went to bed, he certainly was going to feel every knock to the head when he did wake up. Just desserts for this yellowed-bellied skink.
Adjusting his grip, the man moved into a rotting docking area, navigating the slimsy boards with ease of familiarity. Any who tried to follow him would soon find themselves in the cold water below, not that any would try to follow this man. He smirked his blackened teeth showing once more. Who would want to ruin the kidnapping of the fool who got them into a war with no end? Life would be better on the morrow. For the town at least.

Slimsy - flimsy or frail.

Added Info -The reasons why some words flourish and others fall by the lexical wayside are often unclear, but what is clear is that "slimsy" is firmly in the latter category: It has very little current use. This shouldn't stop you from using it though; "slimsy" is a blend of "slim" and "flimsy," and its meaning should be pretty apparent to your audience if you're careful with the context. The word was first used in the mid-19th century and was at its peak of popularity in the early 20th, but who knows? Maybe the 21st century is seeing its revival.
