You think ectomorphs can't get fat ?

I don't even look like a typical ecto anymore bro but that doesn't mean that my somatype has changed.
It's not like a don't have the balls for cardio or anything. That's just a dumb thing to say. It's not that I don't wanna do it but I'm afraid I'm gonna lose to much weight to fast.
I make myself love cardio if it contributes to a good looking body. I dont give a **** bro
How much pounds a week would still be good to lose every week ?
I thought that 2 lbs was about the maximum...
