Is this a lyric from a song? Because this is not a common saying in English. The speaker may be comparing himself to a wooden spoon because he often gets used by people? I'm not sure though. The quote looks like something you would analyze in Literature class.

You need to include the whole quote - in this case, it matters. "wooden spoon" in this case means that his (her) parents punished him (her) by hitting him (her) with a wooden spoon. Over the past 60 or so years, in the US, fewer and fewer parents discipline their children using corporal punishment. The person saying this is commenting on their age and their parents' child-rearing styles.

I was tempted to downvote your question, because you left out the most important word of the quote! Angela was correct, but answered in a very obtuse form, so much so that I didn't even understand what she meant. The quote was "I'm a wooden spoon, lead paint, no seat belt, bed of pickup riding SURVIVOR", and it was written on a shirt with each of the things that the person survived on a different line. So - the meaning is: I'm a wooden spoon Survivor. I'm a lead paint Survivor. I'm a no seat belt Survivor. ... So - the person did not say they were a wooden spoon, they said that they survived ( being hit with ) a wooden spoon. 'Lead paint' refers to the fact that lead paint was common earlier, and most people grew up well despite that. etc...
