Which phrase is an example of Kerouac using slang
as part of his informal diction?
As we rode in the bus in the weird
phosphorescent void of the Lincoln
Tunnel we leaned on each other with
fingers waving and yelled and talked
excitedly, and I was beginning to get the
bug like Dean. He was simply a youth
tremendously excited with life, and
though he was a con-man, he was only
conning because he wanted so much to
live and to get involved with people who
would otherwise pay no attention to him.
- On the Road, Jack Kerouac

"get the bug"  is an example of slang.

no its not a run on sentence however i think you meant wet suits not sours also a run on sentence would be like surfers surf all winter long in southern california by using wet sours to keep them warm and the live their all year long  

sensory details?

so i`m assuming you are writing something from a bats (the animal) point of view. if this is the case, you can use sights, sounds, feelings, and tastes.

and idk what you mean by domain, but all of the sensory details will depend on where the bat is.

a bat doesn't see color very well, so its surroundings will be dulled.

it can hear super well. so maybe it can hear the insects on the ground

feelings. you can imagine how a bat would feel from its perspective. it all depends on where it lives.

maybe it can taste the salt in the air, or smell water, or something. all of these details are completely dependent on where it is located.

hope this .
