What does 38 Degrees 6 mean?

The song 38 Degrees 6 is really upbeat, and to be honest, I especially like it too, it's very grounding, and it seems to be a staple in square dancing now.

It's impossible to escape from you, like a fish swimming in the sand

I know there's no end in sight, but I'm not afraid to break my head and bleed

Loving you is a mirage, like a foamy swim

Illusionary and unfulfilled, the first time I saw you it was hard to talk about it

Heartbeat trembles, embracing this oasis

The warmth of the tenderness, I gave up the whole forest to leave behind. I've given up the whole forest to leave behind my love and sorrow

Like the first time I saw your eyes, time stops flowing backwards

I'm burning up the universe, the temperature is like an electric current

At 38 degrees 6, I can't escape from you

Like a fish swimming in the sand, I know that there's no end

The first time I saw you, my heart is shaking, embracing this oasis

The passionate tenderness.
