vomicough

When someone coughs in such a guttural and sickly manner that bystanders may believe that the person has vomited.

Damn it sounded rough in there. Were you puking or was that just a vomicough?

"I thought I was going to spew, but i just gagged and vomicoughed when I saw that 2 girls and a cup video. Ughhhh....."
