One class of compounds I haven't seen mentioned yet are alkynes.
In organic synthesis classes we've had to synthesise a number of small alkynes and all of them were really awfull, with a very low smelling threshold.
Couldn't wash the smell of your hands or out of your clothes very well.

I remember the smell of phenylacetylene, but it's fresh-baked bread compared to phosphines.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

In undergrad I made quite a few batches of 3,5-dithiahepta-1,6-diyne. Basically https://en.wikipedia.org/wiki/2,4-Dithiapentane but with ethynyl groups on the ends instead of methyl. It made the whole lab smell like weird
truffles. Years later I still don't like truffles very much.
I agree that phenylacetylene isn't bothersome.

It's not the worst of the worst but after prolonged exposure to cumene (2-phenylpropane) I think it's one of my least favorite odors. During the
pandemic even small amounts would persist in my disposable masks and I would smell it all day. Makes me nauseous just thinking about it.

I think the worst smelling chemical I ever smelled is the product of heating of MSG on aluminum foil.
It smells like things that were in a closed space for long, except it's much more pungent and also reminiscent of tobacco smoke.
Always trust your first idea, especially if you only have one.
