It means the bytes received by Squid do not parse as an HTTP request.
Squid only supports HTTP 0.9 / 1.0 / 1.1 protocol as input, with a few
other port-80 protocols which use HTTP syntax such as ICY streaming
media. Or in specific builds of Squid HTTPS port 443 traffic.

You can enable debug_options 33,5 to get some more details about what
the parser found. Usually a lot of them means your network is filled
with software abusing port 80, or the proxy is otherwise listening on a
port which is in active use by non-HTTP protocols.
