Kukkad is a Punjabi word for a cock, a rooster. It's also used for chicken, the cooked one.
Here, the meaning of Kukkad is someone who is a new target, in the college. It's like a 'bakra', but then it's Kukkad kamaal da, that is a wonderful chicken, a wonderful target to hit on.
Making it a little simpler, you can take the analogy of a new, wonderful chick in the college. The difference here is that it's a guy that is being talked about here.
