How about this:

ps aux | grep "^username\b" | awk '{print $2}' | xargs kill

That grep option will catch the username only if it exactly matches the
first column of output from "ps aux". The caret "^" specifies that the
string must be at the beginning of the line. The "\b" specifies that the
string is a word (is followed by non-word characters like whitespace or
end-of-line).
