It is in your very best interest to hang with live deaffies and try your vocabulary face to face. It is ever so much more entertaining. The best entertainment comes from learning ASL only to sign a "good" word incorrectly - such as "coffee" or "soda pop".
Ya know, like walk up to your mama and say "mama, what does sh*t mean??" If she slaps you - you know you said it right. Sort of the same with deaf folks.... except you may expect gales of laughter if you sign it wrong.
Hey- waves hand - did you hearing kids every try lip reading?? OOOh, ya gotta see this and see if you can get it -
