No you can't call any kind of weed 'skunk' because skunk is a specific and DIFFERENT type of plant than normal.
OK when I went to the marijuana museum in Amsterdam last year, I can mix what I learnt with my own knowledge and tell you the following.
'Weed' is a darkish green and all comes from the Sativa plant. It may be spliced with another type of Sativa (like the difference say between Salvia Divinorum, Salvia blue etc) but its all basically Sativa to develop a cross breed and therefore more potent weed. It smells different to skunk. Resin is generally pressed from the oils of sativa.
In England we call regualar grade sativa 'commersh' as in 'commercial' ...generally not very potent and full of seeds.
Skunk is short for skunk weed, so named because it smells very strong, and is a different type of plant to Sativa. Any body who even half knows what they are doing would not confuse sativa weed with skunk weed. Apart from the smells which are very different, skunk has few or no seeds, is much lighter in colour, and should be streaked with orange flecks, which is from the colour of the flower, or bud.
Any dealer could call there gear skunk...but its only skunk if its actually skunk..basically you can even get shitty skunk, but its still more potent than sativa weed, which henceforth I shall just be calling weed. but skunk is skunk and weed is weed
Sensi is short for sensimelia and is indeed a seedless (and usually more potent) weed. People sometimes call high-grade sativa weed with little seeds 'sensi' but this is a mistake as Sensimelia is actually a different strain from Sativa. You can get purple haze as well which is a loverly weed...smeels like sativa weed (strong) and filled with purple specks (from the flowers) hence its name. i think people also mistakenly say that purple haze is hallucinogenic weed, well all weed / skunk is hallucinogenic. (however you spell)
Supertodd has made some good points.
The thing with weed and skunk is you can call it what you fooking want..like pills, a lot of it is just named by the dealer to sound good. It might still be a shit product.
Also you get thai sticks, which is litterally weed from thailand grown on/around a stick...if you can get it on the stick it shoudl be good stuff because people rarely use sticks to gorw it outsideof thailand, as i understand.
I don't know how it is in other places but a lot of weed and skunk in the uk, skunk mostly, is home-grown. By this we mean not grown in your own house, but on your own turf, ie in the uk. Vast warehouses with complicated hydroponics units that can produce a product *good* enough to rival that of imported stuff.
But you can usually tell the imported stuff by the smell, if you are experienced. for example sativa weed grown in jamaica is as potent as skunk from the UK, and since staying in jamaica, we get certain weeds that smell just like the plants over there, because it is almost like skunk, but not. Crossbreed, maybe?
i'm rambling now...
