YES. For me, "scream" connotes a high-pitched, piercing or shrill sound. I was also going with the laziness/lack of creativity, but I was curious how it came across to others. There is also the point of what one considers a scream. I guess that's really at the root of why using the word bothers me.

I haven't read too much fic lately where someone screamed as they came, but I come across it every so often-- even in otherwise really well-written fic. =/
