Learn English – single word for dark smelly fart / farting without noise

In our local language (India->Maharashtra->Kolhapur) we have two different words for fart.

1. When a person farts with (hearable) noise (smelly or not smelly) we call this farting 'Padla'(male=पदला) / 'Padli' (female=पदली).
2. When a person farts without noise and we come to know because of dark smell, we call it 'Thuski'(ठुस्की).

So what is this 'Thuski' called in english?

No doubt everybody will be having their own calling name for this.
After some answers, i edited the question a bit.
I want a single word (no multiple words) with locality name as i have mentioned. So, please tell the word with your locality.
