Is the slang word freaking invented by blacks?

It's impossible to definitively say that any slang word was "invented" by a specific group of people. Slang is constantly evolving, and words and phrases spread organically through different communities.

While it's true that many slang words and phrases have roots in Black American Vernacular English (AAVE), it's not accurate to claim that all slang originated from one specific group.

"Freaking" as a slang intensifier has been around for decades and likely emerged from a mix of influences. It's important to acknowledge the diverse origins of slang and avoid attributing its creation solely to one group.
