Do You Know Your Different Types Of Third Wheels?

The third wheel is an interesting creature and can exist in many different forms. Not to sound like I'm describing them as animals but in the grand scheme of things a couple will generally want to be left to their own devices...sometimes third wheels just over stay their welcome and sometimes they won't even be aware of it...do you know your different types of third wheels?
The third wheelman
You started the night with a wingman/woman/person which went very successfully for you but now as the night nears its end things haven't been as great for you wingperson. And that has left you in a dilly of a pickle. You now have the task of trying to drop this wingperson as their services are no longer required...AWKWARD!
The savage third wheel
Of course you may want to share the goods with your wingperson as seen in Oliver Stone's film 'Savages' whereby Blake Lively was shared by two lesser actors who's respective names escape me (not that I care enough to search) but all I know is that in that film that would be a prime example of a 'savage third wheel'...
The relaxed third wheel
This one works both ways and is likely both the couple and the 3W are cool with it. You probably pop around, have pizza, watch the Liverpool game/Kardashians and pop home.
The oblivious and annoying third wheel
Similar to the above situation but one sided as the couple can't seem to get across to the wheel how much they don't want them around or that they've outstayed their welcome..then again they may no want to hurt their feelings and not say anything to them.
The quest for the fourth wheel
The couple return the favour and help find the third wheel someone to keep him company. Probably because of a combination of all of the above...
The we don't care you're here third wheel
The third wheel in this situation has seen the couple in more revealing situations than him or her would wish.....the couple almost don't care they're there. This is probably seen more in younger teenage relationships whereby the male of the couple is as horny as a dog in heat or equally an emo couple whose 3W is too emotionally distant to even realise he's a third wheel.
The drunk wheel
The one who is the only single person amongst a crowd of couples....ALWAYS. The drunkest at every partay...and the one that truly doesn't give a fiddlers about hooking up with anyone...future spinster or bachelor fo shizzle..
