koosinustratsioonlike
Koosinustratsioonlike is a term that appears to be a neologism, likely a portmanteau combining "co-sinus" and "frustration." The "co-sinus" aspect suggests a relationship or a parallel with the trigonometric function, the cosine. This might imply a cyclical, oscillating, or perhaps even a diminishing return scenario, akin to how the cosine wave behaves. The "frustration" component clearly indicates a feeling of annoyance, disappointment, or being blocked in achieving a goal.
When combined, "koosinustratsioonlike" could describe a state of ongoing, cyclical frustration that doesn't resolve or improve.
