English to Spanish Other Slang wiretap transcription

I am actually back-translating into Spanish a translation into English of an original Spanish dialogue (hmpf!)
It's a conversation over the phone, between drug dealers.

The phrase is,

"I was going to bring you inside so you could see the size, but XX was with you... It's all grounded up".

No other mention to this specific piece of conversation.

Any idea of what "grounded up" means in this context?

Thanks a lot!
