Foamer 

Foamers are boring train nerds who spend their entire waking time watching live train webcams on youtube. Many are former railroad workers who are retired and can't let the past go and still want to be at work. They sit in chatrooms of said cams all day long, spouting off random mind crushingly boring facts about trains coming in and out of view of the camera in order to try to impress others watching. They utilize cb radios and the internet to stalk railroad services to try to impress people with their incredibly boring facts.

That big foamer Bob was in the train chat again today, we learned so much! 499 left Kamloops 00:30 arrived Revelstoke 09:24. The GCP is the same as the Harmon HXP. No DPU. Probably a Z train. bnsf r-chi476 wb 10:29 with empty sand cars for oregon, il
