Okay, this is my entry into the black hole of cheese. This list would only be brought out in dire situations of Orkiness. Rip it apart as you wish. There is a variant I am considering which really takes the horrible to an extra level, so let me know which you prefer:

List 1:
HQ
Big Mek - Kustom Force Field
Warboss - cybork body, 'eavy armor, power klaw, squig

Elites
2x 10 lootas
10 Kommandos - Snikrot, 2 burnas

Troops
2x 12 slugga boyz, nob (klaw, bosspole)
Trukk - reinforced ram
11 slugga boyz, nob (klaw, bosspole) --> Warboss goes here
Trukk - reinforced ram
20 shoota boyz, nob (klaw, bosspole)
19 shoota boyz, nob (klaw, bosspole) --> Big Mek goes here
3 nobz (might squeeze in points to make them individual, or at least give them a bosspole)
Battlewagon - big shoota, reinforced ram

Heavy Support
Battlewagon - big shoota, reinforced ram
3 killa kans - big shootas
3 killa kans - grot zookas

Both 20 man mobs go into the battlewagons. The nobz pick their noses in my deployment zone, maybe even hold an objective if I'm lucky, all while going to ground anytime they're shot at.

List 2:
HQ
Big Mek - Kustom Force Field
Warboss - cybork body, 'eavy armor, power klaw, squig

Elites
2x 10 lootas
3 nobz
Battlewagon - big shoota, reinforced ram

Troops
2x 12 slugga boyz, nob (klaw, bosspole)
Trukk - reinforced ram
11 slugga boyz, nob (klaw, bosspole) --> Warboss goes here
Trukk - reinforced ram
20 shoota boyz, nob (klaw, bosspole)
19 shoota boyz, nob (klaw, bosspole) --> Big Mek goes here
3 nobz (might squeeze in points to make them individual, or at least give them a bosspole)
Battlewagon - big shoota, reinforced ram

Heavy Support
3 killa kans - rokkits
3 killa kans - big shootas
3 killa kans - grot zookas

Essentially we just do away with snikrot, use that spot for a dedicated transport battlewagon, and use the freed up heavy support slot for another squad of kans.

To take this up to 2250 I'd just start filling out fast attack options, which would likely be stormboyz, as that's what I have. Alternatively I could throw in some buggies but god do I hate those models.

This is basically a variant on a list proposed to me by MVBrandt with a bit more static firepower & a couple of larger squads of boyz in lieu of more buggies, which I've neither been a fan of nor have the models for to put into great effect.
