Arachnerd 

A low life specimen obsessed with Arachnids and Arachnid culture. These Arachnerd's usually like to please themselves by letting spiders and other eight legged creatures crawl in or on their genitalia for sexual satisfaction.

Honey don't put you pet spider on your penis again, youll become an Arachnerd

Not here to fornicate with arachnids 

A more nuanced take on ‘not here to fuck spiders’. A classic Australianism expressing that things of little consequence or excessive moderation are not worthy to be undertaken.

Further context, similar to ‘having bigger fish to fry’.

“Hey Ellis, last drinks just got called. Pint of pale and mezcal chaser?” says Toph.
“Not here to fornicate with arachnids.” he replies in support of the offer.

Arachnads 

Spidey's gonads

"My spider-sense detects tingling sensation in my arachnads" said Spidey as he looks at Mary Jane in a wet t-shirt.

arachnid 

Surely one of the most successful groups of animals in the history of this planet. There are arachnids on every continent (except Antarctica, obviously). Arachnids include spiders, scorpions, mites, ticks and the like. Though it is very rare for soft-bodied animals to survive, in fossil form, the oldest known fossil spider is 380 million years old, and there are even older fossil scorpions and sea scorpions known. Whenever I watch a tarantula or scorpion I can't help feeling I'm being given a viewpoint on an early age of life on this planet.

An example of an arachnid: a tarantula, a member of the oldest group of spiders which did not spin webs, merely used silk to line their burrows.

Arachnegrophobia 

Fear of black spiders from the ghetto. Also, fear of negroes with spider tattoos.

So I got this cool black widow tattoo on my penis, but now Jennifer won't go down on me because of her arachnegrophobia! :(
