Rustacean 

A Rustacean is a homosexual child predator species that is mostly found in basements. They like to lurk on the internet and rant about how rewriting every existing piece of software in Rust will improve our future and stop climate change, despite the language itself being very unreliable and unstable. Rust is so unstable that a program written in it has a 49% chance of self-destructing.

Usually a Rustacean will claim that Rust is better than C++ because it is "memory-safe," unlike C++.
In reality, Rust doesn't have any runtime memory safety checking or a garbage collector. Only the compiler predicts and warns the developer.

Rustaceans write code that simply tricks the compiler.

Rustacean: Rust is the best language out there! Not only is it low-level, but it is also memory-safe with minimal memory management. If we rewrote {software written in either C or C++} in Rust, then it would be so much better!

Ordinary developer: If you hate memory management so much, then why opt for a low-level language to begin with? There are languages like Go, C#, and Java that have nearly the same speed as a compiled language yet are actually memory-safe with garbage collection.

Rusty Crustacean 

The Rusty Crustacean is a sexual act where; a female lays on her back and her partner puts their thumb inside the vagina and four remaining fingers inside the anus of the female. Then, the partner squeezes their fingers together (reenacting the movement a crustacean's claws make when closing) causing fluctuation of the vaginal and anal region of the female. Maximum pleasure is promised if performed correctly.

Dude, I totally gave Candice the ol' Rusty Crustacean last night... She loved it.
