Laid Up - You’re so turned on in bed that you’re thinking about sex so

You’re so turned on in bed that you’re thinking about sex so much your brain is going to explode. You’re too busy daydreaming to do anything else.

I was laid up and I couldn’t stop thinking about my girlfriend. I got distracted.

Laid up with my lover and I forgot to eat. I was too busy thinking about sex.

I was laid up and my brain turned into a meatball.
