The lyrics to "Trism" do sound like something a JT Time Traveler might say to a girl.
'Trism' could almost be an anagram for TimeTravel + Prism...
Cryptic message in the song maybe meaning a guy and a girl traveling on parallel time lines.
'Course, I'm sure B52 didn't have Time Travel in mind when they wrote it.
But what if the song was used as a cryptic message to a girl from John Titor?
I know it might sound far out there, but you never know.

John loved leaving cryptic messages, and someone did write the title of the song in a book to a girl,
so it had to have some meaning.
TRISM
She has to leave
She has to go
The fastest way
Is by trism
Steps off the curb
Stella Corona hopes for the best
To be home by sunset
Gotta be home by sunset
She asked me to give her a ride
She said she had to go
Dropped her off by the trism
Through the atmosphere by prism
Go trism, trism
Trism, trism, trism
Gotta keep, gotta keep movin' on
And gotta keep movin', and gotta keep movin', movin'
Gotta keep movin' and gotta, gotta keep on
It was a human race to get away, year
And then back again
Like the sun bends light through a prism
She bends herself through the trism
Like the sun bends like through a prism
She bends herself through the trism
In the smoky streets of the night
She pulls the lever and then bright light
Trism, trism
