Silent but deadly 

A fart that is not heard, but smells so horrid that it could kill; also: Silent but violent, SBD

Your farts aren't that bad when compared to Grandpappie's ol' silent but deadlies.

silent sally 

A young, good looking girl with one major flaw- the bitch doesnt talk. A typical relationship with a Silent Sally includes hundreds of pointless text messages in which you both discuss the same bullshit in an attempt to get laid. In person, she really wont say anything unless you ask a question, in which the typical response consists of one word.

You- "How was your day?"

Silent Sally- "Good."

You- "Anything cool happen?"

Silent Sally- "No."

You- "Wanna come over?"

Silent Sally- "No."

You- "Why not?"

Silent Sally- "Soccer."

You- "Ok, see ya later then..."

Silent Sally- "Bye."

silent sex 

what married people do when they're too cheap to get a second hotel room, and have to have sex with two sleeping 7 year olds in the next bed. Usually accompanied by silent shushing faces, muffled giggles and careful movements so as not to make the bed creak. Culminates in silent grimaces during climax.

Stan and Diane got a great hotel in Maui for their 10th anniversary, but ending up having to have silent sex, since it was too pricey to get a second room for the twins

when someone refuses to speak to you, just to be mean, even thought you ALREADY appologized and meant it.

Chandi: I'm sorry. They're actually not bad.
Geb: *silent treatment*
Chandi: So... Bitter?
