A plugin for a browser may help... I was personally going to suggest Dolphin but since that didn't work for you maybe try copying the word into a new tab Google define word search...? It's at least save you the time taken to open up a new app....

BUMPY BUMPYIs there an app that will allow me to highlight a word while browsing the web and get its definition similar to how iOS does? I found and installed iknow Dictionary for Dolphin Browser but I would need to copy and paste into it for my definition.
