nasal-ingressive voiceless velar trill 

Linguistics joke. There's a fake IPA symbol to go with it, that looks like a pig snout.

It's linguistically correct description of, well, the sound pigs make.

First-year linguistics students can be humiliated by asking them to include nasal-ingressive voiceless velar trill in their presentation of rare and difficult-to-pronounce sounds in the West African languages.

nasal grenade 

When you flick a booger in to an unsuspecting group and everyone scatters.

We were eating dinner last night and I lobbed a nasal grenade in to the adjoining booth.

Nasal Helmet 

When you pull your girl’s freshly worn panties (stains and skid marks a plus) over your head with your eyes peering thru the leg holes and the gusset running down your nose like a knight’s nasal helmet.

The nasal helmet was a type of combat helmet characterised by the possession of a projecting bar covering the nose and thus protecting the center of the face.

Rachel left her workout panties on the floor when s he she took a shower so I made myself a nasal helmet and enjoyed her ripe, pungent fragrance.

Nasal trumpet 

During oral copulation, the gag reflex kicks in simultaneously with ejaculation, causing the jizz to flow retrograde out the nasal passage creating a trumpet like sounds.

I think I got a sinus infection from the nasal trumpet my boyfriend gave me last week...
