Kidding?

Any dictionary, dude -- it's wicked easy to find no matter how apathetic you might be. Here, I'll get you started:

insinuate

slide (oneself or a thing) slowly and smoothly into a position

"the bugs insinuate themselves between one's skin and clothes"

[like the govt insinuating itself under your skin?]

--Oxford

: to introduce (someone, such as oneself) by stealthy, smooth, or artful means

Insinuate comes from the Latin root sinuare, meaning "to bend or curve"

[kinda slippery, snakelike?]

--Merriam-Webster

: to gradually make (yourself) a part of a group, a person's life, etc., often by behaving in a dishonest way — usually + into

[exactly as the govt does?]

He gradually insinuated himself into her life.

--Britannica

to introduce or work into gradually, indirectly, and artfully to insinuate oneself into another's favor

If you say that someone insinuates themselves into a particular situation, you mean that they manage very cleverly, and perhaps dishonestly, to get into that situation.

--Collins

​insinuate yourself into something (formal, disapproving): to succeed in gaining somebody’s respect, trust, etc. so that you can use the situation to your own advantage

[making sense yet?]
